Arthur Fry (born 1931) is a retired United States inventor and scientist. He is credited as the co-creator of the Post-it note, an item of office stationery manufactured by 3M. As of 2006, Post-it note products are sold in more than 100 countries.
Fry was born in Minnesota, and subsequently lived in Iowa and Kansas City. He received his early education in a one-room rural schoolhouse. During his childhood, he reputedly made his first foray into engineering by building toboggans from scrap lumber. He went on from those early efforts to study chemical engineering at the University of Minnesota. He has 3 children and 5 grandchildren.
In 1953, while still enrolled in undergraduate school, Fry took a job at 3M (then called Minnesota Mining and Manufacturing Company) as a new product development researcher. He worked in new product development throughout his career at 3M until his retirement in the early 1990s.
