Hans Baumann

Hans D. Baumann (October 12, 1930 – March 25, 2025) was 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 was an expert on aerodynamic noise of gases and he was a frequent contributor to the NEWSMAX Magazine INSIDERS website.

Life and career Baumann came to the United States from Germany in 1953, as an exchange student. He held 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 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.

Awards Honorary Member of the International Society of Automation Life Fellow Member of the American Society mechanical Engineers.
