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.
