Apr. 12—Dayton businessman Harold Robert Rieck Jr., 96, of Dayton, died Monday, according to his obituary.

A gathering of family and friends is set for 4 to 8 p.m. April 19 at Carillon Park Kettering Family Education Center, 1000 Carillon Blvd., Dayton, with a celebration of life scheduled for 6 p.m.

Rieck Services, the family's mechanical contracting company, celebrated 125 years in business in 2017.

"Customers in Dayton understand quality, and we work hard to provide that," Rieck told the Dayton Daily News that year.

"It's unbelievable," he added. "I love Dayton, and Dayton loves me back."

Herman Rieck started a small business on Wayne Avenue in the 1890s. The company installed sheet metal roofing and furnaces around the city, and Herman Rieck became famous for speedy service — flying through the streets on horse and wagon.

In 2015, the company said Harold Rieck sold his shares in Rieck Services after six decades to spend time with family and to focus on his philanthropic work.

Rieck Services, a commercial mechanical contractor at 5245 Wadsworth Road, was sold to four members of the company's board of directors, who purchased shares from Rieck and Vice President Larry Cottle at the time.

"For more than 120 years, the Rieck family has led the business, beginning with Harold's great-grandfather Herman F. Rieck," Chief Executive Doug Mayse said in a statement in 2015. "Harold is the fourth generation of the Rieck family to lead the business and he will continue to serve as a consultant to the board of directors."

The company, which had more than 200 employees in 2015, provided maintenance and construction services in the areas of heating, air conditioning, ventilation, sheet metal fabrication, temperature controls and energy solutions.
