Mark Benson (born Mark Müller; Jun 19, 1888 – May 1965) [1] was a Bohemian German engineer, best known as the inventor of a supercritical boiler.. Benson was born in the Sudetenland, and his original name was Müller (he changed his name during World War I to hide his German origin).
The second Benson boiler began operation in 1930 without a pressurizing valve at pressures between 40 and 180 bar (4 and 18 MPa; 580 and 2,611 psi) at the Berlin cable factory. This application represented the birth of the modern variable-pressure Benson boiler. After that development, the original patent was no longer used.
