Marjorie Kaltenbach Lueloff was both an artist, and an active member of Milwaukee's vibrant art community of the 1950s. She began her art studies at Kemper Hall, a female seminary in Kenosha, Wisconsin, studying under Edith Jane Bacon. After graduating from the University of Wisconsin-Madison, she went on to study at the Art Institute of Chicago and the Hubert Ropp School of Lake Forest and Chicago. In Bloomfield Hills, Michigan, near Detroit she studied with John Carroll, a well-known artist in the 1940's, who'd studied at the Art Students League in New York. He painted a portrait of her titled "Lady in Red", which was featured in Life Magazine.
She worked in both oil and pastel, concentrating on portrait and still life painting. Her own work appeared in a number of group shows in Milwaukee and other parts of Wisconsin. She also exhibited at the Arts Center in Sarasota, Florida.
Mrs. Lueloff was a board member of Wisconsin Painters and Sculptors. She was also listed in Who Was Who in American Art.
Both Mrs. Lueloff and her husband Reuben T. Lueloff, who founded a manufacturing company of lightweight engines in Grafton, Wisconsin (Power Products Corporation) in 1946, were very active in the Wisconsin art community, both as collectors and patrons. He served as a trustee of the Milwaukee Art Institute, the predecessor to the Milwaukee Art Museum. Both were very active in the Walrus Club, a group of creative, artistic Milwaukeeans, who promoted and enjoyed art, put on lavish costume balls and, generally, had a wonderful time during the fifties.
Along the way, they amassed a fine and extensive collection of work by Wisconsin artists including Carl Priebe, Dudley Huppler, Mary Nohl and Dorothy Meredith, all of whom were close friends.
Their interest was not limited to well-known art and artists. They were also active sponsors of the Ozaukee County Rural Art Show. The aim was to encourage young artists in a rural area. To this end they offered not only prize money, but also purchased the works of winners and put them on display.
