William "Bill" Cook of Greenville, passed away Wednesday, Jan. 10, 2018, in Santa Barbara, California. He was born Dec. 1, 1934, in Greenville, the son of Arthur M. and Anne H. Cook. Bill was a graduate of Greenville High School in 1953, and a graduate of Michigan State University in 1957. He was known to most as a standout football and track athlete, which included being named all-conference in both sports, and becoming a state champion high hurdler. Because of his accomplishments, he was inducted in the Greenville High School Hall of Fame Class of 2012. When he eventually moved back to Greenville, Bill also put his focus back into the schools he grew up in. He volunteered for 30 years as a track meet official, and was part of the committee that helped make building the first track at Greenville High School a reality, along with Harold Steele and Leo Marshall. In 2006, Bill and Harriette were among the first donors to support the United Memorial Hospital expansion project, which made a new surgery and patient care center possible. In recognition of their early donation, in addition to those made by Byron and Dee Cook and Jeff and Caroline Cook, their name is honored on the Cook Family Inpatient Center and Cook Family Surgery Center at what is today called Spectrum Health United Hospital. In 2014, Bill and Harriette made the lead gift to make the United Hospital OB Department expansion and renovation possible. With the vision of Bill and his brother, Byron, they were responsible for the development on the western side of Greenville in the 1980s with Hathaway Properties. Bill married the love of his life, Harriette Clark, on Feb. 1, 1958. He was co-owner of Cook Investments and Southwestern Oil Company.
