Frantisek Zaviska (1879-1945), a Czechoslovak physicist.

Karel Petr (1868-1950), a Czech mathematician known for the Petr–Douglas–Neumann theorem in plane geometry, which he proved in 1908, and was independently rediscovered by Jesse Douglas in 1940 and Bernhard Neumann in 1941.

Miloslav Valouch (1878-1952), a Czechoslovak physicist and mathematician. He studied mathematics and physics at the Faculty of Philosophy in Prague. In 1909, he was appointed professor at the Faculty of Science in Prague. After 1918, he worked at the Ministry of Education and National Education until 1927. After his retirement, he continued to be active in the Union of Czechoslovak Mathematicians and Physicists.

Juraj Hronec (1881-1959), a Slovak mathematician, was professor of mathematics at the Czech Technical University in Brno. He recognized the importance of mathematics in science and technology and focused his research on application to technical problems. His academic lifetime achievement includes three areas: scientific, educational and public. Research activities focused primarily on differential equations.

Homage to Ada Lovelace (1815-1852)
Ada Lovelace (Lord Byron's daughter) was an English mathematician and a pioneer in the science of computers.

"She was the first to recognise that the machine had applications beyond pure calculation, and to have published the first algorithm intended to be carried out by such a machine. As a result, she is often regarded as the first computer programmer" (Wikipedia)
