A German thermal engineer, Diesel invented the internal-combustion engine that bears his name, producing a series of increasingly successful models that culminated in his demonstration in 1897 of a 25-horsepower, four-stroke, single vertical cylinder compression engine. It was an immediate success and earned him a fortune. In 1913, while traveling by steamer to London for a business meeting, Diesel disappeared, presumably having fallen, jumped, or been pushed overboard. Was his body ever found? Discuss
