Tallahassee, Florida – David James Mueller, a dedicated educator, community servant, and mathematics enthusiast, passed away at the age of 80 on August 26, 2025.

He started at City College of San Francisco in 1963, later transferring to Graceland College in Iowa, where he obtained an Associate of Arts in Science.

Mueller’s academic endeavors culminated with a Bachelor of Science in Mathematics and Chemistry from the University of Wisconsin-Madison and a Master of Science in Mathematics from the University of Michigan. He completed his formal education with a doctorate in Mathematics Education from Florida State University between 1971 and 1974.

After years of dedicated service, he retired in 2012 as a Mainframe Computer Systems Security Manager.
