Howard Wilson Emmons

Howard Wilson Emmons (1912–1998) was an American professor in the department of Mechanical Engineering at Harvard University. During his career he conducted original research on fluid mechanics, combustion and fire safety. Today he is most widely known for his pioneering work in the field of fire safety engineering. He has been called "the father of modern fire science" for his contribution to the understanding of flame propagation and fire dynamics. He also helped design the first supersonic wind tunnel, identified a signature of the transition to turbulence in boundary layer flows, and was the first to observe compressor stall in a gas turbine compressor. He initiated studies on diffusion flames inside a boundary layer, and Emmons problem is named after him. He was eventually awarded the Timoshenko Medal by the American Society of Mechanical Engineers and the 1968 Sir Alfred Egerton Gold Medal from The Combustion Institute.
