Luboš Perek is celebrating his 100th year

Founding fellow of the Learned Society and its doyen, astronomer doc. RNDr. Luboš Perek, DrSc, is celebrating his 100th birthday on 26 July 2019. He is an indelible part of history as the person who helped define cosmic space, he was the first to point out the issue of cosmic waste and was also a teacher to the most important Czechoslovak astronomers. Let us express our respect and admiration of the extraordinary scientific career of a person who worked tirelessly and continues to work. The Learned Society wishes Mr Perek health, optimism and joy in the oncoming years.


The Academy of Sciences of the Czech Republic has appealed to the Hungarian President to support academic freedom

On Friday 19 July the Academy of Sciences of the Czech Republic and the Learned Society of the Czech Republic sent a letter to Hungarian President János Ánder, in which they state their concerns regarding the situation in respect to management and funding of scientific activities in Hungary. An act, according to which not the Academy of Sciences, but a thirteen-member political committee, will decide on research, funding of scientific activities and establishment or closure of scientific workplaces, will come into force on 1 September.


The loss of Learned Society Fellow prof. Josef Koutecký

We regret to inform that prof. Josef Koutecký, a fellow of the Learned Society, a renowned physician and the founder of paediatric oncology in this country, passed away on 5 July 2019 at the age of 88. He founded paediatric oncology here in 1964 and a separate paediatric oncology department was then established at the Faculty Hospital in Motol, Prague in 1978.
