zicman feider (1903–1979) was a jewish romanian acarologist, a remarkable researcher and a gifted academic, whose work continues to influence by many generations of biologists, some of whom studied zoology under his supervision. his name as a researcher is forever associated with the enigmatic group of acari a.k.a. acarina (a taxon of arachnids that contains mites and ticks), for which he arduously worked to perfect their taxonomy. alone or in collaboration with his numerous disciples, he described and created 1 phalanx and 2 sub-phalanxes, 16 families and 8 subfamilies, 40 genera, 4 subgenera, and 145 species new to science.
