Franz Maria Feldhaus (26 April 1874, in Neuss – 22 May 1957, in Wilhelmshaven) was a German engineer, historian of science, and scientific writer.
"[3] Born in Neuss as son of a pharmacist, Feldhaus studied electrical engineering without receiving his degree.
Later on the occasion of his 50th birthday in 1924 he was awarded an honorary doctorate by the RWTH Aachen in recognition of his accomplishments in the field of the history of science.
[8] Feldhaus' Geschichte des technischen Zeichnens is translated into English and published in 1960-63 as "The History of Technical Drawing."
