Solomon Harper
Solomon Harper (born in Poplar Grove, Arkansas, on August 8, 1893[3]) was an electrical engineer and inventor[4] known for creating the first electrically heated hair roller[5][6][2][7] and 28 other inventions.
Harper worked for various railways performing jobs like section head, construction and other locomotive work. In 1914, he applied for his first patent for his block system which he invented to prevent train collision. It was designed to prevent rear and head on collision and to prevent trains from running into open switches, to automatically reduce train's speed at dangerous places, and to stop trains at railways junctions.[8]
During the course of his career, he struggled to receive recognition and compensation for his inventions.[9] Harper was trained as an electrical engineer[10] and was a veteran. He was a politically active communist, and organized at least one march to picket the White House about unemployment in 1930.[11]
