Karl Lenhardt, founder and managing partner of Lenhardt Maschinenbau GmbH (now Glaston Germany GmbH), has died at 82.

Lenhardt was a pioneer in the glass industry, developing the process for manufacturing insulating glass for windows and facades. More than 150 patents were ultimately designed based on his developments throughout his career.

“With Karl Lenhardt, we are losing a personality for whom people were always at the center of his thoughts and actions,” says Dietmar Walz, senior vice president of Glaston’s insulating glass business unit. “For him, the company’s success was based not only on his inventive thinking but predominantly on the personal commitment and expertise of his loyal, long-standing employees.”

Lenhardt founded Lenhardt Maschinenbau in 1966 at 27 and retired in 2002.
