Jack died May 15, 2009.  

He was born in Chicago and graduated from Exeter. At Princeton he majored in economics and belonged to Cannon. Jack was the stroke of the 1948 150-pound crew that won the Thames Challenge Cup at the Royal Henley Regatta.

After graduation, Jack worked a few years for A.B. Dick, but essentially his entire business career was with the Dukane Corp., a family-owned company in St. Charles, Ill., that was founded in 1922. In the early 1970s, when his father died, Jack took over ownership and operation of the company, which then manufactured equipment in the electronic, electro-mechanical, and optic fields. By 2005, when Jack was chairman of the board, the company had evolved into a global manufacturer and marketer of advanced technology products such as ultrasonic plastic welders, aviation products, and data video projectors.  

Jack was active in local business and nonprofit organizations, and in regional and national professional associations.  

He was the father of two daughters and two sons by his first two marriages, both of which ended in divorce. Another son, John III ’86, died in 2000. Our condolences go to his surviving children and his wife, Cheryl.
