Viktor Grebennikov

Viktor Stepanovich Grebennikov (Russian Cyrillic: Виктор Степанович Гребенников; April 23, 1927 - April 10, 2001) was a Soviet Russian artist and autodidact interested in entomology (insects) and apiology (bees), studies that drew him to a belief that some insect flight is caused by "cavitary structure effect," the structure of chitin acting as a form of anti-gravity, on which basis he claimed to have built a single-person flying platform.
