We were shocked as we received the news of Zlatko\u2019s passing. We were already planning to visit him during the upcoming summer, or at least to come together to celebrate his 85th birthday, as we did his 80th a few years ago. We are still not able to overcome his passing \u2013 he will be greatly missed for years to come.
For decades Zlatko Kva\u010dek was a distinguished person in the palaeobotanical research community. Even in the 1970s and \u201880s his work was widely known internationally, even though he worked and lived behind the iron curtain. His knowledge and results were extraordinary; accordingly, he was recognized first by western Europe, and then in North America and Asia. He produced these results while remaining always a nice and humble person, who was encouraging but not pushy. Palaeobotany was his life, and he prioritised helping young researchers starting their careers in this field, not only in the Czech Republic, but also in the neighbouring countries of Central Europe.<\/p>\n\n\n\n

Zlatko Kva\u010dek was born on July 28, 1937 in Prague, as the second child of the physician Dr. Ji\u0159\u00ed Kva\u010dek and Marie Kva\u010dkov\u00e1. In his childhood, he was already interested in the natural sciences; he prepared his own herbarium, in\ufb02uenced by his grandfather, who was a school principal. In his high school years, he met his future wife, Hanka. They were married on July 6, 1961, and this loving relationship lasted for 59 years, until his recent passing. The marriage gave them two children, Ji\u0159\u00ed and Lucie. Zlatko began studying at the Faculty of Science of Charles University in Prague in 1958. He received his diploma in geology, and his diploma thesis was already about palaeobotany: \u201cTertiary plant remains from the Julius Fu\u010d\u00edk Mine, in \u017del\u00e9nky near Duchcov.\u201d From 1960 to 1963 he was employed as a geologist in the mining company Geologick\u00fd pr\u016fzkum n. p. Dub\u00ed, where he worked in the exploration of non-coal resources. From 1963 to 1965 he was a graduate student at the Institute of Geology of the Czechoslovak Academy of Sciences (\u010cSAV) in Prague. During that time, he worked on his Ph.D. thesis under the supervision
of Prof. Dr. Franti\u0161ek N\u011bmejc. In 1966, he defended his Ph.D. dissertation, entitled \u201cEvolution of brown coal swamp \ufb02ora in Bohemia during the late Tertiary.\u201d He worked for \u010cSAV until 1991. In the meantime, in 1985, he defended his DrSc. thesis on \u201cCuticle analysis of Neogene trees from Central Europe\u201d at the Academy\u2019s Institute of Geology and Geotechnology.<\/p>\n\n\n\n

Since 1991, Zlatko was active in the Faculty of Sciences at Charles University, first as an Associate Professor, then promoted to full Professor in Palaeobotany in 1998. He retired in 2003, but the scientific world could not notice it, because he continued to publish an abundance of scientific papers and participated in several international conferences. During his 80th birthday celebration, one of his students, Jakub Sakala, pointed out that Zlatko\u2019s publication activity between his 70th and 80th year was comparable to an active young scientist. Zlatko always worked in a team \u2013 almost all of his publications have multiple authors.
At the beginning of his career, he worked with his excellent colleges in Prague: Erv\u00edn Knobloch, \u010cestm\u00edr B\u016f\u017eek and Franti\u0161ek Hol\u00fd. Unfortunately, none of them are alive today; they passed away a long time ago. His palynology co-worker, Magda Konzalov\u00e1 with whom he co-authored numerous papers, thankfully is still with us. Later Zlatko established many international connections. His oldest and longest palaeobotanical collaborations were with Prof. Harald Walther from Dresden and Prof. Dieter Mai from Berlin, which also turned into strong, life-long friendships. The authors of this obituary were also honoured to work with him for many decades.<\/p>\n\n\n\n

Lilla Hably\u2019s Memories of Zlatko Kva\u010dek<\/strong>
In 1977 Zlatko organized an international conference, \u201cAdvances in Angiosperm Palaeontology\u201d at Liblice Castle in Bohemia, at that time still behind the iron curtain. This was my first experience of participating in such a conference, and it
inspired me to continue in this field of study. Many palaeobotanists participated in this conference, not only from western and eastern Europe, but also from the USA. This was the first time that palaeobotanists from the East and West met, since earlier palaeobotanical conferences were only available for the western world. Later, he also organized several symposia. His major event was the 7th European Palaeobotany-Palynology Conference in Prague in 2006.<\/p>\n\n\n\n

At first, he was able to build collaborations only within the so-called socialist countries. Based on his excellent work, he was invited into western countries as well, where he studied and revised not only the fossil Tertiary \ufb02ora, but also searched for comparisons in the recent herbaria. He knew many of the European collections. He was fond of saying, \u201cThe best locality is the collection\u201d. He had an amazingly retentive memory. He not only remembered in which collection he saw a certain fossil or taxon, but many times even the actual cabinets. He also had an extraordinarily detailed memory for the properties of each taxon. The application of cuticle analysis in Tertiary palaeobotany is also a major theme of his work. Whenever available, he investigated the epidermal anatomy of fossil leaf specimens, and he encouraged others to do so as well, while he also acknowledged the limitations of this method. He prepared the samples by himself, which is a very time-consuming task. One of his main areas of focus, the revision of older collections applying cuticle analysis, resulted in international collaborations, especially in the descriptions of Tertiary \ufb02oras. He was an excellent taxonomist. His research projects resulted in the publication of important monographs on Palaeogene and Neogene Taxaceae, Fagaceae, Juglandaceae, Platanaceae, Theaceae and Ericaceae from Central Europe, including the investigation of gross-morphology and cuticular analysis of fossil and living taxa, as well as comprehensive \ufb02oristic monographs of particular localities such as Kundratice, Bechlejovice, Markvartice, Vesel\u00ed\u010dko, Star\u00e9 Sedlo, B\u00edlina and several others. We are not able to list all his results and conclusions \u2013 they can be found in his bibliography. Zlatko had always two important principles in mind, which were often neglected by earlier generations. First, the identification of real botanical affinities of the fossils, for which he used cuticular analysis whenever
possible. The second, adhering to the nomenclatural rules. Zlatko\u2019s research projects have also been focused on taphonomical and palaeoecological aspects of fossil sites, with a particular aim to reconstruct the Tertiary vegetation and environment. In addition, Zlatko took part in other international projects, like the \u201cIUBS Plant Fossil Record\u201d and the \u201cDatabase of Palaeogene and Neogene European Neogene Floras\u201d.<\/p>\n\n\n\n

Zlatko Kva\u010dek is the most well-known European palaeobotanist, but his name is familiar to palaeobotanists all over the world. First of all, he studied Tertiary and Late Cretaceous \ufb02oras of the Czech Republic, but later engaged in the investigation of localities from all over Europe and even North America. His scientific interest covered a wide range of topics and methods. He published more than 200 papers. In 2018, he won the Honorary Membership award of the International Organization of Palaeobotany, which could not have gone to a more fitting person.<\/p>\n\n\n\n

His loveable personality and his good sense of humour fascinated all around him, because he was not only a world famous palaeobotanist, but also an excellent teacher, husband, father and grandfather.<\/p>\n\n\n\n

It was more than 43 years ago, in 1977 that I first met Zlatko Kva\u010dek. After graduating from the university, I was granted a month\u2019s study visit to Prague in the scope of the cooperation between the Hungarian and Czechoslovak Academies of Sciences. At that time, study trips were allowed only to the so-called socialist countries, and I chose Prague. The palaeobotanical department of the Czechoslovak Academy of Sciences was located in Sp\u00e1len\u00e1 street, no. 49, which, we already knew, was the focus of palaeobotany in the 1970s. In fact, Prague itself was a well-known palaeobotany centre. Besides Zlatko, I should mention Magda Konzalov\u00e1, \u010cestm\u00edr B\u016f\u017eek, Franti\u0161ek Hol\u00fd and Erv\u00edn Knobloch \u2013 all worked here at that time. In spite of the political isolation of this era, they were all outstanding
palaeobotanists, and they made contacts with colleagues not only from other parts of Europe but also from overseas. Well, I got acquainted with cuticular analysis here in Sp\u00e1len\u00e1 49. I learned from Zlatko how to prepare fossil cuticles. Later I turned to him with several palaeobotanical questions via mails, which is unimaginable now for the young colleagues \u2013 it took 2\u20133 weeks to have answers to questions. We arranged our projects and study trips in this way.<\/p>\n\n\n\n

By means of bilateral projects between the Academies in the 1980s and 1990s, I could travel to Prague for a week each year, which was a real professional refreshment for me. We could discuss palaeobotanical questions which arose through the year. Later Zlatko payed visits to Hungary nearly every year, which even my family waited for; the world-famous scientist even played with my little children!<\/p>\n\n\n\n

We worked mostly on Oligocene and Pliocene \ufb02oras of Hungary, but together visited other palaeobotanical sites also from the Miocene age, like Ipolytarn\u00f3c and Magyaregregy. Together, we collected fossils from the early Oligocene \ufb02ora of Eger-Kiseged, and from the completely new Pliocene palaeobotanical sites in G\u00e9rce and Pula. It was hard field work during many hot summer days under the burning sun. We studied together the collected material, the result of which was a monograph. Zlatko visited several palaeobotanical collections of Hungary. He
worked generally in the Botanical Department of the Hungarian Natural History Museum, since he was interested in the famous collection of Prince Lobkowitz, containing lots of type specimens from Ettingshausen\u2019s monograph on the localities around B\u00edlina in the Czech Republic. He studied numerous taxa, like Sloanea, Byttneriophyllum, Platanus neptuni, Tilia, Comptonia, Berberis, Ilex and several others. Moreover, he also investigated Eocene materials in the Geological Institute of Hungary, and identifed and revised many specimens from Eger, Wind-brickyard in the collection of the M\u00e1tra Museum.<\/p>\n\n\n\n

Dear Zlatko! It is really painful to bid farewell to You! It is still incomprehensible that You have gone, but we keep You in our memories forever! In my early career you kindly helped me, giving lots of energy. I am very beholden to You for being helped, for knowing you, for learning from you and for calling you not only my teacher but also my friend!<\/p>\n\n\n\n


Johanna Eder\u2019s Memories of Zlatko Kva\u010dek<\/strong>
In September 1980, while I was a student and had just started to work on my PhD, I spent four weeks in Prague to study palaeobotany and to learn cuticle analysis with Zlatko Kva\u010dek. At that time, this was a rare chance for a student from a western country, and it became possible by a scholarship from the Austrian Academy of Sciences. At this time, Zlatko\u2019s lab was hosted in a \ufb02at in Sp\u00e1len\u00e1 49 close to the V\u00e1clavsk\u00e9 n\u00e1m\u011bst\u00ed and the National Museum. It was my first day in Prague; it was foggy, nevertheless I was wondering why the windows of the lab looked frosty white instead of transparent. Zlatko explained me that the glass had turned white from working with hydro\ufb02uoric acid, which he frequently used to dissolve sediment adhering to the leaf remains. He would put the samples between the double glass windows. This was my first long-lasting impression from Prague. In the following weeks, Zlatko offered me without reservation all his broad knowledge that could be relevant for my thesis and I soaked\/absorbed all information. Zlatko had studied geology, but he also had a remarkably broad botanical knowledge in taxonomy, plant sociology and ecology. The monograph of Erv\u00edn Knobloch and Zlatko Kva\u010dek on the Miocene \ufb02ora from the western margin of the Bohemian Massif was already published, and Zlatko held photoprints of the leaves and cuticles, which he offered me because their quality was better than the printed plates. These pictures were extremely useful for my studies and I still keep them as reference.<\/p>\n\n\n\n

During this stay Zlatko arranged meetings with the late \u010cestm\u00edr B\u016f\u017eek and Franti\u0161ek Hol\u00fd. He also organised a field trip to Maxim Gorkij mine in North Bohemia. Although in those days it was not at all usual to invite colleagues from the other side of the iron curtain to one\u2019s home (registration at official hotel was required), Zlatko and Hanka were extremely kind hosts, inviting me for meals together at their \ufb02at. At this occasion I also met first Ji\u0159\u00ed, Zlatko\u2019s and Hanka\u2019s son who was a pupil. From this time onwards I first visited Zlatko almost regularly every year in Prague to perform comparative studies, and after the opening of the iron curtain in 1989, Zlatko also regularly visited Vienna to perform studies in the palaeobotanical collection and the herbarium at the Natural History Museum, as well as in the Geologische Bundesanstalt and the Institute of Botany at the University of Vienna. Zlatko passionately worked in many foreign collections, in Europe, N. America and China. The opening of the iron curtain must have been a mental liberation for him, which eventually offered him the possibility to further broaden his expertise and to network his immense numerous pieces of botanical and palaeobotanical knowledge. This development fostered Zlatko\u2019s incredible productivity in publishing.<\/p>\n\n\n\n

The \ufb02ora of Parschlug is one of the most important Neogene ones, because it is extremely diverse, and numerous fossil-species were described by Franz Unger and Constantin von Ettingshausen in the 19th century. Large collections are hosted by different institutions in Austria and abroad. The revision of this \ufb02ora was a tremendous effort, and we jointly visited different collections. Zlatko\u2019s famous memory and sovereignty in nomenclature were essential to perform this revision, which we published in 2004.<\/p>\n\n\n\n

Zlatko was very open-minded to new ideas, and unbigoted to collaboration. This is evident from the wide array of his coauthors. With the start of automatic data processing, in the late 1980s, a database of Palaeogene and Neogene \ufb02oras of Eurasia was started. Zlatko did not hesitate at all to get acquainted with a personal computer and to contribute with the input of data for Czech localities. We put strong emphasis on high and updated taxonomical resolution of the data. Colleagues from many European countries joined in, among them Harald Walther, Dieter Mai, Ewa Zastawniak, Lilla Hably, R\u0103zvan Givulescu, Emanuel Palamarev, Yuri Teslenko to mention only a few. They provided data that became the basis for several collaborative studies in the following years. Zlatko also strongly supported the idea to develop a semiquantitative method based on leaf physiognomy and putative autecology of fossil taxa to assess major vegetation features, and to visualise the results by geographically mapping them. This attempt was further developed into the Integrated Plant Record (IPR) vegetation analysis, which was first published in 2007, and since then has been applied and developed further.<\/p>\n\n\n\n

Thanks to Zlatko\u2019s abilities and enthusiasm as university teacher, the Czech and the Slovak republics can be proud of a next generation of palaeobotanists with complementary specialisation: Jakub Sakala (fossil wood), Vasilis Teodoridis (fruits, quantitative evaluations to assess climate and vegetation), Ji\u0159ina Da\u0161kov\u00e1, Nela Dol\u00e1kov\u00e1, Marianna Kov\u00e1\u010dov\u00e1 (Tertiary pollen), Jana Zaj\u00edcov\u00e1, Helena Soukupov\u00e1 (Tertiary plants), Ji\u0159\u00ed Kva\u010dek (Zlatko\u2019s son, Mesozoic, Tertiary and Quaternary \ufb02ora, and head of the Department of Palaeontology, National Museum), Jana \u010cepi\u010dkov\u00e1 Cretaceous plants), Josef P\u0161eni\u010dka, Milan Libert\u00edn (Carboniferous plants). I am not aware of other countries that can be proud of such a well-established palaeobotanical community \u2013 dating back to the time of Kaspar Sternberg.
Apart from science, I experienced many enjoyable evenings with Zlatko and Hanka in their \ufb02at, where Hanka always prepared delicious Czech dishes, even when she must have been tired after a full day\u2019s work as dentist. On such occasions, we communicated in a peculiar mixture of German, Czech, Russian and English.<\/p>\n\n\n\n

We all know about our finiteness, nevertheless it is hard to accept it. We are deeply mourning that Zlatko has left us for ever. Dear Zlatko, please accept our sincere thanks, for all you taught us, for all you showed us, and simply for having had the chance to be friends with you.<\/p>\n\n\n\n

Steven Manchester\u2019s Memories of Zlatko Kva\u010dek<\/strong>
My first regular communications with Prof. Zlako Kva\u010dek were by airmail as I became interested in various genera shared between the Tertiary of central Europe and western North America. Together with \u010cestm\u00edr B\u016f\u017eek in 1988, we began working on Pteleaecarpum fruits shared between Oregon and Bohemia, which he later found to match with the living Asian genus Craigia. We would send typewritten versions of the manuscript back and forth by airmail for reciprocal editing and eventually succeeded with co-authored publications at a time when collaboration between eastern and western block countries was still very limited and slow. Other projects included Tetraclinis foliage and cones and Platanus neptuni leaves and infructescences, all similarly shared between North America and Europe. He kindly invited me to visit Prague on an exchange visit funded both by US National Research Council and Czechoslovak Academy of Sciences in 1989. He not only shared the facilities of his lab and museum collections, but introduced me to other colleagues in Prague, notably Erv\u00edn Knobloch, \u010cestm\u00edr B\u016f\u017eek, Magda Konzalov\u00e1 and facilitated my examination of various collections. He and his wife Hanka were so welcoming. This gave me the opportunity to meet his son Ji\u0159\u00ed for the first time, who was at that time in high school \u2013 resulting in another long-lasting friendship.<\/p>\n\n\n\n

During my exchange visits in Prague, Zlatko volunteered to take me on long road trips in his car to visit other European colleagues and collections. In this way we travelled together, with the opportunity to meet Mr. Zden\u011bk Dvo\u0159\u00e1k at the B\u00edlina Mine headquarters, Harald Walther in Dresden, Leon Stuchlik and Eva Zastawniak in Krakow and Johanna Eder in Vienna, and received permission to study the historical collections of Franz Unger in Graz. We each took along our film cameras and portable stands in order to photograph specimens pertinent to our various \ufb02oristic and taxonomic projects. He also gave me good advice and paved the way for me to meet other paleobotanists with whom new collaborations developed, for example Mikhail Akhmetiev, Lilla Hably, Dieter Mai and Edoardo Martinetto.<\/p>\n\n\n\n

Zlatko\u2019s abilities with cuticle preparation are legendary. Drawing on his knowledge of chemistry, as well as his experience with trying various different approaches, he developed procedures for maceration of modern and fossil cuticles that would give excellent results. This required not only methodological expertise, but special networking skills to obtain the necessary chemical reagents that could be very difficult to access during local communist times. Later, when Zlatko was visiting Gainesville, I complained that I had found a fern-like leaf that I suspected to be cycad, but could not get good results from the cuticle. The cuticle was peeling of the rock, seemingly well preserved, but my macerations could not resolve the cell outlines. He offered to help and took my unsatisfactory preparations into our chemistry lab to process by his own methods. In less than 30 minutes he returned with beautiful preparations: \u201cI think you did not leave it long enough in the nitric acid\u201d. This led us to see that we had discovered a new species of Eostangeria \u2013 the first recognition of this genus from North America, which previously was known only from the Geiseltal of Germany.<\/p>\n\n\n\n

My basic education lacked formal training in Latin, so I was always relying on Zlatko\u2019s help for composing new species epithets with the proper suffxes to comply with gender of the generic name. Nevertheless, you will find in my publications some mistakes of Latin \u2013 instances where I forgot to ask Zlatko to
kindly double check my Latin composition.<\/p>\n\n\n\n

Zlatko helped me in writing a successful collaborative proposal to the US National Science Foundation that funded some of our activities in 1997 \u2013 2000: \u201cU.S.-Czech
paleobotanical research on Tertiary plant disjunctions of North America and Europe\u201d. This facilitated exchange visits in both directions, and I was happy to have the opportunity to host him and Hanka in travels across the US. We had a
memorable trip to Yellowstone National Park, followed by visits to various Paleogene localities in Wyoming and Montana, including camping trips with Hanka volunteering as our chef in the field!<\/p>\n\n\n\n

I was impressed by Zlako\u2019s advanced knowledge of the places we were visiting, and what he could teach me about the vegetation and geology of my own country, as well as his insights when we would visit paleobotanical collections of
various museums across the US and Europe.<\/p>\n\n\n\n

I enjoyed participating in the celebratory symposium on the occasion of Zlatko\u2019s 80th birthday in 2017, and was eager to see him again on occasion of the International Organization of Palaeobotany Conference that had been scheduled for this year, September 2020. Through a sad sequence of events, this meeting was postponed due to the Covid-19 pandemic, and Zlatko has not lived for us to celebrate him in person. I am not prepared, emotionally, to accept that he has left us. This year we co-authored our nineteenth paper together \u2013 a treatment of Paleocene Trochodendraceae fruits and foliage that features his expertise on epidermal anatomy. I am so thankful for his guidance and encouragement over the years. Another thing that impressed me about Zlatko was his enduring loyalty to colleagues. He very often completed the manuscripts of friends who had perished before him, like Hol\u00fd, B\u016f\u017eek, Knobloch and Walther. Now it is up to us to carry on and to help with the projects and aspirations that he, himself, could not complete.<\/p>\n\n\n\n
