Robert H. Friedrich (June 30, 1891 – August 8, 1966), better known by the ring name Ed "Strangler" Lewis, was an American professional wrestler and trainer. During his wrestling career, which spanned four decades, Lewis was a four-time World Heavyweight Wrestling Champion and overall recognised officially as a five-time world champion. Considered to be one of the most iconic and recognizable sports stars of the 1920s, often alongside boxer Jack Dempsey and baseball player Babe Ruth, Lewis notably wrestled in over 6,000 matches (many of which were real contests) and lost only 32 of them.
