Lawrence Brown co-founded the Minneapolis Ronald McDonald House, fought in a segregated unit in World War II and donated his body to science after he died March 14, the Star Tribune reported.
Brown held many different jobs over the years, the Star Tribune reported, from assistant football coach at Minneapolis North High School to establishing a tax-withholding system in Uganda.
His most loved role, however, was "Papa," according to the Star Tribune.
Among 89 other descriptions in a list that Brown's children and grandchildren gave him on his 90th birthday, No. 78 read, "Believer in people."
Brown is survived by his wife, Jo, and his two children, Kevin and Janine.
