Donald (Bud) Brock, 88, passed away peacefully on September 1, 2021, with his beloved wife of 66 years, Zeal, at his side. Eldest son of Donald and Elizabeth Brock, he is predeceased by his sister Cynthia Higgins and survived by his brother, Edson Brock (Sandy), and sister Linda Pinto. Bud was the proud father of three children, Andrea Finley (Mike), Neil Brock (Laura), and Joel Brock (Susan); grandfather of Katelyn Finley, Sarah Finley, Dylan Brock, Hayley Brock Moten (Derrick Moten), and Rachel Brock (Matthieu Pacaud); and great-grandfather of Kaylen Moten. Bud and Zeal were always together and loved to travel throughout the United States and Europe. They enjoyed going to the theater and symphony, walking in the Chicago Botanic Gardens and at the lakefront, eating out, and visiting friends and family. Bud grew up in Skokie and left the area only to go to Millikin University in Decatur, Illinois, where he met Zeal Zimmerman. After finishing college and marrying, they moved back to the area and have lived in Evanston for over 64 years. He spent most of his working life working for Chandler's, Inc. in Evanston, beginning part-time at age 14 and then full-time after college. Bud was an active member of the Unitarian Church of Evanston for over 60 years. Bud was very active with the Boy Scouts, serving as Scoutmaster of Troop 12, taking the troop to the Ma-Ka-Ja-Wan Scout Reservation, working with the Wood Badge program, and receiving the Vigil Honor in the Order of the Arrow. After retirement Bud found a new passion, drawing. He took classes at Noyes Cultural Arts Center, Evanston Art Center and at the Art Institute of Chicago. He also enjoyed curating art shows at Three Crowns Park, his residence in Evanston. Memorial gifts may be sent to the Unitarian Church of Evanston Endowment Fund, Boy Scout Camp Ma-Ka-Ja-Wan, or the Evanston Arboretum. A memorial service will be held at a later date.
