Heinz Steinitz
Heinz Steinitz was born in Breslau, Germany (now Wroclaw, Poland) on April 26, 1909, to Walter Steinitz (1882-1963), a cardiologist and zoologist, and Marta Schindler Steinitz (1885-1926). He grew up in Breslau and was greatly inspired by his father to study science and to be an active Zionist. He studied medicine from 1927-1933 in the universities of Breslau, Freiburg and Berlin. Although he passed the Medical Board examination in 1933, and would have started work in a hospital in Berlin and in the Jewish hospital in Breslau, he was prohibited from practicing by the Nazi regime which came to power that same year. Together with his wife Ruth Aber Steinitz (1907-1995), a medical student as well, he left Germany in 1933 and immigrated to Palestine.
Heinz Steinitz
The national and international reputation of Heinz Steinitz is reflected by names in his honor given to more than twenty newly discovered fishes, marine organisms and amphibians, listed in the Biographical Etymology of Marine Organism Names. Some names were given years after he passed away. 
The fish species "Tylognathus steinitziorum" (discovered and named by Dr. Curt Kosswig in 1950, now called Hemigrammocapoeta nana) was dedicated to Walter Steinitz and his son Heinz Steinitz.
