Trautwine with compliments N. Simin Moscow, Russia.” Joukowsky (1847-1921), following his graduation from Moscow University, entered graduate studies at the Petersburg Military Institute of Communications. In 1872 he was appointed mathematics teacher at the Moscow Technical College, where he worked up to his death in 1921. He wrote much on the laws of motion of solids and fluids but made his most important contributions to aeronautics. He is considered one of the fathers of aerodynamics. “Joukowsky’s memoir on his improved form of the hydraulic ram, which first appeared in 1899 as The Hydraulic Ram. This improvement was based upon his hydrodynamic studies between 1890 and 1900, which had yielded a theory of water-hammer that not only explained the physical and mathematical nature of this phenomenon, but made it possible to calculate it.”–Roberts & Trent, Bibliotheca Mechanica, p. 178. Very good copy. From the Franklin Institute Library with several of their more subtle markings. Ex Bibliotheca Mechanica.
