James (Hap) Sharp

James R "Hap" Sharp was a keen amateur racer and Texas oil man who became a close confederate of Jim Hall in the development of the Chaparral sports cars during the early and mid-1960s. He ran a Cooper-Climax in the 1961 and 62 US Grands Prix and a Lotus-BRM in the 1963 event. He also drove the Lotus to a career best seventh in that year's Mexican Grand Prix and he again competed in the US and Mexico in 1964 with a Rob Walker Brabham-BRM. Sadly, personal problems resulted in his eventual suicide.
