Hans D. Baumann is a German-American inventor and engineer. He has registered over 200 patents and produced 105 publications. He is known internationally as a valve specialist and is an expert on aerodynamic noise of gases.
Baumann came to the United States from Germany in 1953, as an exchange student. He holds degrees from [Case institute of Technology (now part of Case Western Reserve University)] and Northeastern University, and earned a Ph.D. in Mechanical Engineering from Columbia Pacific University.
Baumann has worked as Chief Engineer at W. & T. Co., a valve supplier in Germany; Manager of Research & Development at Worthington S/A in France; Director of Engineering at Cashco, Inc., in the U.S.; Vice President of Masoneilan International, Inc.; and Senior Vice President of Technology for Fisher Controls. In 1977, he founded H. D. Baumann Assoc., Ltd., manufacturing control valves; the company was subsequently acquired by Fisher Instruments, and is now part of Emerson Process Management.
Baumann is a licensed Professional Engineer in four states and a member of Sigma Xi, the Scientific Research Society.
