The remainder of his life was spent in private experimental work, which he carried out in his workshop and laboratory at Godalming. His interests covered a wide range and included mechanical, automobile and electrical engineering, as well as chemistry, astronomy, aviation and radiography. He made wireless sets from the earliest days of the industry and built model locomotives and also produced a number of inventions, including a very early electric clock. Mr. Buttemer was a pioneer motorist, his first car being an 1897 11 h.p. Benz, the engine of which he converted into 3 h.p., and he travelled 77,000 miles in this machine. He was a founder member of the Royal Automobile Club and an original member of Brooklands Automobile Racing Club, winning many cups in motor trials in the early days of motor cars.
