Joseph A. Tecson, 86, a longtime resident of Riverside and attorney who served as a Cook County Commissioner and on the boards of directors for many private and public organizations and agencies, died Jan. 11, 2015.

Mr. Tecson served in the U.S. Navy as a radioman in airplanes aboard the aircraft carrier USS Shangri-La. After his service in the Navy, he became an attorney and passionate public servant.

He was a founding member of the law firm Chuhak & Tecson, where he was in charge of the firm’s governmental and healthcare divisions. For more than two decades he served as the municipal attorney for the village of North Riverside and as an arbitrator for the American Arbitration Association.

Mr. Tecson was a delegate to the 1970 Illinois Constitutional Convention, which was responsible for writing a new constitution for the state. He was appointed chairman of the committee that drafted the executive article of the constitution.

He served as a commissioner, and the first Asian-American, on the Cook County Board for five years and served on the committee that oversaw Cook County Hospital. In addition, he served on the board of directors for MacNeal Hospital and the Chicago Zoological Society.

Passionate about the subject of expanding public transportation, he helped build the region’s transportation infrastructure by serving as the first chairman of the board of the Regional Transportation Authority, writing the definitive article on the creation of the RTA. He also served on the board of Metra.

Mr. Tecson is survived by his wife of 60 years, Caroline Tecson (nee Rees). He was also the father of Andy (Nancy Hagen) Tecson, Sarah (Rick) Pavon and David (Cheryl) Tecson; the grandfather of Andrew (Megan), Jeffrey, Michael, Julie, Luke, Matthew, Jack and Grant; and the great-grandfather of Audrey.
