Aerosol research in Czechoslovakia before 1970

The Czechoslovak Republic was born on October 1918 as one of the results of the World War I. During this period, two scientists contributed to the aerosol science research. They were Leo Wenzel Pollak and Frantisek Behounek. Following World War II, the Czechoslovak Academy of Sciences (CAS) was formed. CAS was the site for a number of aerosol researches. Since about 1960s, scientific contacts and cooperations with Western countries started to be easier. However, during the period of time between 1970-1990 several scientists, working groups and even institutes were dispersed or closed.
