McCarty had been fighting a four-year battle against the disease, which has no known cure. The cancer had forced him to sell his contracting company, but it spawned a charity to research the disease.
Mr. McCarty and son Darren formed the McCarty Cancer Foundation in 1998. Headquartered in suburban Detroit, the foundation held many charity events and fundraising drives to support research of myeloma.
The family is asking that memorials be made in the form of a donation to the McCarty Cancer Foundation, P.O. Box 32444, Detroit, MI 48232.
Mr. Mintz started in his father’s sheet metal business, Shaker Tinning Co., after serving in World War II. The company then expanded to include a heating operation. When his father moved to Florida, Mr. Mintz took over the business.
In 1954 he started the Shaker Air Conditioning Co., which at one point had five branches. Later, he and some partners inaugurated Shaker Mechanical Corp.
After the company was sold in the mid-1980s, Mr. Mintz moved to California.
