||Moritz Abraham Stern (b. 29 June 1807) was a German mathematician. Stern was interested in primes that cannot be expressed as the sum of a prime and twice a square (now known as Stern primes). He is known for formulating Stern's diatomic series, which counts the number of ways to write a number as a sum of powers of two with no power used more than twice. Pic.

||Eduard Čech (b. 29 June 1893) was a Czech mathematician born in Stračov (then Bohemia, Austria-Hungary, now Czech Republic). His research interests included projective differential geometry and topology. He is especially known for the technique known as Stone–Čech compactification (in topology) and the notion of Čech cohomology. Pic.
