In Memoriam

Carl Wangman - Jan 2013Carl Wangman (1933 – 2022)

Carl was born September 29, 1933 to loving parents, Holger and Dorothy Wangman in Waukegan, Illinois. Carl was a three-letter athlete and graduated Valedictorian of Waukegan High School, before heading east to attend Yale University. At Yale, Carl studied History, made a host of lifelong friends, and graduated with Honors in 1955. Despite acceptance at some of the best law schools, Carl chose a different path and joined the Navy. During his four-year tour of duty as a naval communications officer, Carl honed his leadership skills and met the love of his life, Janice, and wasted no time asking for her hand in marriage. They were married on August 16, 1958 in Janice’s hometown of Williamsville, New York.

Carl and Janice relocated back to the Chicago area where they would spend the rest of their lives together. Carl started a long, distinguished career as an association management professional in 1966, owning two association management companies, serving as chief staff officer for more than 30 professional societies, and earning several lifetime achievement awards. As a strategic thinker, gifted communicator and passionate leader, Carl was known for operating with the highest standards of integrity, helping to grow virtually every organization he served.

Family, friends, employees, neighbors, shipmates, Yale classmates, Yale hopefuls, clients – all were beneficiaries of Carl’s genuine wit, charm and generosity. A modern-day Renaissance man, Carl had an enduring curiosity about the world and deep interest in the lives of those who crossed his path. Carl was a world traveler, voracious reader, smart dresser, sports junkie, avid gardener, aggressive tennis player, weekend chef and golfer, sun and water worshipper, devoted mentor and godfather, gifted storyteller and public speaker, active theatergoer and consumer of all forms of film. He loved the Chicago Cubs (like the rest of his extended family) and the Green Bay Packers (he rode that bus alone). Carl left this world a better place, leaving a void that all who knew him are called to fill by remembering what Carl taught them.

A celebration of Carl’s life will be held when the flowers start to bloom again. Donations can be made to the Chicago Botanic Garden, an organization Carl deeply cared about.
