Anna Matalová is Emeritus Head of the Mendelianum of the Moravian Museum that continues the historical research started by the Franz (now Moravian) Museum founded by the learned Agricultural Society in 1817. She was the first (and the last) assistant to Jaroslav Kříženecký after his release from the communist prison. Since then, she has devoted her life to research into Mendelian history and its presentation. She was editor of the academic journal Folia Mendeliana. After the Velvet Revolution, and until her retirement, she was the Head of the Mendelianum in Brno and Chairperson of the Czech Committee for the History of Science and Technology in Prague. Shortly after the fall of the so-called Iron Curtain, Anna began organizing the international Mendel Forum conferences to facilitate intensive and open communication among researchers and experts from the West and the East. Thanks to her endeavour, the Mendelianum has now been located in the authentic rooms of Mendel´s Agricultural Society in the historical heart of Brno. She also has highlighted other places connected with Mendel´s life and authored Mendel´s Path in Brno. She was instrumental in the establishment of the Fund for Mendel´s native house (farmstead of Mendel´s parents) in Hynčice (now part of Vražné), allowing for its reconstruction as a place for cultural meetings. In her exhibitions and scientific publications, she has presented Mendel´s accomplishments in context with actual cultural, social and scientific topics. Her husband, son and daughter consider Mendel as a member of the family. Eva Matalová is a leading Research Scientist at the Institute of Animal Physiology and Genetics of the Czech Academy of Sciences and a Professor at the University of Veterinary Sciences in Brno. She has “inherited” her interest in Mendel from her mother, Anna. Eva has been active in the Mendelianum since her PhD studies, organizing annual Mendel Forum conferences in the 21st century and other activities focused on students and youth (Junior Mendel Forums, Wednesdays with Mendel, DNA afternoons, Science in Action, etc.). Eva proposed the idea of the International Mendel Day on March 8, and established an International Mendel Network consisting of expert 3 scientists and historians. She was the initiator, facilitator and guarantor of the project Centrum Mendelianum, based on Anna´s concept of Mendel´s accomplishments as a naturalist. Eva feels honoured to assist with publication of this book on the occasion of the bicentennial of Mendel's birth. With love to our genetic offspring, Tommy and Luky.
