The correct spelling of his name is Lenz but it has been Anglicised to Lentz in English-speaking countries.
Life and career
In 1888, Lentz founded his own machine factory in Vienna. At an exposition in honour of Alessandro Volta in Como in 1899, his first steam engine won the first prize. At the Exposition Universelle (1900) in Paris, it won the Grand Prix while Lentz himself was awarded the gold medal.
In total, Lentz acquired some 2000 patents. He is best known for his steam valve gear with oscillating and rotating cams to actuate poppet valves. He also developed an eponymous form of locomotive boiler, the Lentz boiler, with a corrugated tubular furnace.
Lentz died on 21 March 1944.
