Article Abstract:
Felix Bernstein, born in 1878 in Halle, Germany, finished his doctorate in mathematics at Gottingen. His involvement in genetics was traced in his statistical analysis of multiple factors in quatitative traits in the early 20s. His greatest contribution was his study on blood group inheritance, the first human markers, with which he proposed the multiple allele alternative in 1925 which corrected the then prevailing two-locus hypothesis. He took his work on blood groups further when he studied the effects of consanguinity. He migrated to the US in 1928 and taught mathematics in a number of universities although his research work had been noted to have declined after this move.

Article Abstract:
Nikolai Ivanovitch Vavilov was one of the USSR's most respected scientists and greatest plant geneticists. He was the head of the All-Union Institute of Plant Breeding, was the author of hundreds of books and articles, was elected VP and Pres of the sixth and seventh International Congess of Genetics, respectively and a recipient of numerous scientific awards. As head of programs aimed to raise agricultural productivity, he relied strongly on systematic collection, hybridization and selection methods, which yielded excellent results despite being time-consuming. Despite these achievements, he was arrested by the government in 1940. He died in detention in 1943.

Article Abstract:
Erwin Schrodinger was awarded the Nobel Prize for his wave mechanics theory in physics, but geneticists remember him for his book 'What Is Life?'. His book influenced several outstanding scientists and greatly advanced the field of molecular biology. Schrodinger's interest in the gene and its stability attracted physical scientists to shift their interest to molecular genetics. He introduced a genetic problem to a fellow scientist that remains to be unsolved. The problem consisted of equations concerning the breeding of horned and hornless cattles.
