  Michael John Cudahy (March 24, 1924 – March 11, 2022) was an American entrepreneur, business executive, and philanthropist.
  
  ## Early life, family and education
  
  Born in Milwaukee, Wisconsin, in 1924, Cudahy was the son of John Cudahy, United States ambassador to Ireland, Poland and Belgium. His grandfather was Patrick Cudahy, founder of the Patrick Cudahy Meat Company.
  
  On August 2, 2007, WTMJ-AM in Milwaukee reported that Michael Cudahy was one of several private investors considering purchasing Midwest Airlines.
  
  ## Career
  
  Along with Warren Cozzens, Cudahy founded Marquette Electronics in 1965 and served as chairman and CEO. The company went public in 1991. After starting with only $15,000 in capital, the company went on to have over $350 million annually in sales. This company created the nation's first central electrocardiographic system at Northwestern University Medical School. The machine became standard in hospitals throughout the United States. The company was also noted for having one of the first on-site daycare centers in the nation.
  
  In 1982, he and Warren bought the failing Patient Monitoring Business Unit from GE (then known as General Electric Medical Systems Division) and combined it with the existing business (primarily diagnostic equipment). By 1998, however, he sold Marquette Electronics (by then known as Marquette Medical Systems) to GE. The company exists today as part of the Clinical Systems division of GE Healthcare, a subsidiary of the American conglomerate. After stepping aside at his company, Cudahy focused his energies on philanthropy and serving on the boards of other companies.
  
  In 1999, according to U.S. Securities and Exchange Commission (SEC) filings, he invested $10 million in TomoTherapy a Madison, Wisconsin, biotechnology start-up. It went public on May 9, 2007, with the stock symbol TOMO. Mr. Cudahy's 10% interest was valued at more than $100 million by September 2007.
  
  He told the story of the founding of Marquette Electronics in the book Joyworks (2002; ISBN 0-938076-17-5).
