Bloomington, Ind. — Gayle Karch Cook, historical preservation activist and cofounder of the Cook companies alongside husband Bill Cook, passed away at 91 this morning. She is survived by her son Carl and daughter-in-law Marcy and their granddaughter, Eleanor.
“Gayle’s spirit of innovation was evident in everything she did. Whatever she was involved in, she left it better than she found it. This was true of her philosophy for the ever-growing company, her extensive efforts in renovating historically significant places, and her daily interactions with other people. That’s her inspiring legacy that we will keep striving for,” said Pete Yonkman, president of Cook Medical and Cook Group.
In 1963, Bill and Gayle Cook created a small company named Cook Incorporated that manufactured three simple medical devices used to treat patients in less invasive ways than common surgical techniques of the time. Gayle was the company’s first quality control employee, meticulously checking the devices Bill made after he finished work each night.
That small company grew into what is today Cook Group, a family of ethical and entrepreneurial companies. Cook Group includes the flagship company, Cook Medical, a global company that invents, manufactures, and delivers devices for treating conditions in almost every system of the body. Cook Group also includes companies in the life sciences, property management, resort, and service businesses.

Bill, Carl and Gayle Cook
The family planned ahead for this event, and nothing will change for employees moving forward. Carl Cook, Gayle and Bill’s son, has been CEO of Cook Group since his father’s passing in 2011. Company leadership will remain the same with Pete Yonkman as president of Cook Group and Cook Medical and Steve Ferguson as Chairman of the Board.
Gayle Karch Cook, born March 1, 1934, in Evansville, Indiana, made excellence her goal in every aspect of her life. She was salutatorian of Bosse High School when she graduated in 1952, and she earned a Bachelor of Fine Arts from Indiana University in 1956. After graduating, she began her career in advertising in Chicago. After marrying her husband, Bill, they moved to Bloomington, Indiana. There, in the spare bedroom of their apartment, they officially began the company that would later become Cook Medical. The company’s focus has always been on the patient, with a goal to make surgeries minimally invasive.
She was committed to creating a vibrant community, as she also served on the board of directors for the Star of Indiana Drum and Bugle Corps, the Bloomington Antique Mall, the Nature Conservancy, Indiana Chapter, and the board of trustees of the Indiana University Foundation.
Gayle was an avid supporter of historic preservation, and she was heavily involved in many restoration projects. She spearheaded about 70 historic preservation and economic revitalization projects, including the much-lauded West Baden Springs and French Lick resorts; Indianapolis’ Central Avenue Methodist Church; and Beck’s Mill and Cedar Farm complex in southern Indiana. The first property she restored and refurnished was the Colonel William Jones House, built in 1835. The house, which is on the National Register of Historic Places, is now a museum open to the public as a State Historic Site. Gayle restored historic sites to their original state, including the James Cochran house, the Illinois Central Freight Depot, the 8-story Graham Hotel, and more than 17 structures in the central square of Bloomington, Indiana.
In addition to her involvement in the restoration work itself, Gayle served on the boards of many restoration organizations. She was on the advisory committee of the Wylie House Museum, the Board of Governors of the Monroe County Historical Museum, the board of the Historic Landmarks Foundation of Indiana, and was an appointee of the State Historic Preservation Review Board. She was also a founder of the Monroe County History Center Annual Garage Sale which has become a staple in the Bloomington community. With every project, Gayle’s philosophy was to restore not just the site itself, but also the character and beauty of the location for present and future generations. Historic preservation wasn’t just good business; it was an investment in the community.
Gayle authored and published two books detailing her passion for Indiana’s history. The first, A Guide to Southern Indiana, was published in 1972. The other, Monroe County in Focus: Portrait of an Indiana County, was published in 1990.
A Phi Beta Kappa graduate of IU, Gayle earned a Bachelor of Arts degree in fine arts in 1956. She and her late husband were generous, far-sighted benefactors of IU’s Jacobs School of Music, School of Education, School of Medicine and Kelley School of Business, as well as supporting IU Athletics, the Wylie House Museum, the Wells Scholars program and research in the College of Arts and Sciences.
