Gennady Vasilyevich Potapenko (Russian: ???????? ?????????? ?????????) (Mar 25, 1894 – June, 1979) was an American radio astronomer of Russian origin.
After the signal discoveries made by Karl Jansky in the mid-1930s, Potapenko (then a Cambridge physicist), along with Caltech physicist Donald Folland and Palomar telescope designer Russell Porter, attempted further researches in 'star static' in 1936.
They were able to confirm Jansky's results with a loop antenna, then a single wire, but were unable to secure adequate funding to continue.
