John Leonard Meanwell (1919–2005) was a Canadian artist and art teacher, known for his abstract expressionist landscapes and figurative work.
His father accepted a position at the Albert Khan architecture firm in Detroit, Michigan, where he worked for the rest of his career.
Jack shared his family's interest in art, and began figure drawing in high school.
An abstract expressionist, Meanwell strove to take the viewer beneath the surface of reality with his dramatic landscapes and figures painted in bright bold colors with energetic brush strokes.
He worked on the McGregory Bay mail boat for his aunt who ran the post office and local store.
Despite this new business venture, Meanwell continued to paint and began showing his work in 1969 in Cincinnati and New York City.
Most of Meanwell's summers were spent in McGregor Bay, Canada, where he found inspiration for his landscapes in the rugged wilderness.
As Meanwell continued his artistic career, his works were shown at almost 100 art exhibits and galleries in the region, beginning in 1969.
The same year, the Mary Ran Gallery presented a major exhibit of forty of his strongest paintings at The Miami University Art Museum in Oxford, Ohio.
