CLINTON, N.Y. — William (Bill) Macartney III — who chaired the board of directors for the Indium Corporation of Clinton — died Sept. 14 from cancer at age 79, the company announced Wednesday.

Macartney was part of Indium for more than 50 years, having joined the company in 1967. He was named company president in 1970.

Under Macartney, Indium Corporation grew from about 20 employees to nearly 1,200 today and from one facility in Utica to 14 locations worldwide.

“The hallmarks of Bill’s leadership were his devotion to the people who worked for him, his caring for community, and his commitment to customers who have relied on Indium Corporation to provide outstanding products that have truly impacted the world,” Greg Evans, CEO, said in a statement.

“Bill believed that materials science changes the world and he made that a fundamental element of the culture of Indium Corporation,” Ross Berntson, president and COO, said. “He provided the platform for our team to continuously look for the next technological advancement.”

Indium is a materials refiner, smelter, manufacturer, and supplier to the global electronics, semiconductor, thin-film, and thermal management markets.

Appointment of a new chairman will be completed at the discretion of the board of directors. Evans remains as CEO and Ross Berntson as president and COO.

Founded in 1934, Indium has global technical support and factories located in China, Germany, India, Malaysia, Singapore, South Korea, the United Kingdom, and the U.S.

Its products include solders and fluxes; brazes; thermal-interface materials; sputtering targets; indium, gallium, germanium, and tin metals and inorganic compounds; and NanoFoil.
