Rufus Riddlesbarger (18 September 1893 – 1968) was an American entrepreneur who marketed a line of contraceptive diaphragms in the 1930s. Under the Lanteen Laboratories brand, Riddlesbarger operated a chain of clinics in Illinois, Wisconsin and Michigan, which were promoted through radio advertising.

Career Riddlesbarger is believed to have been an Army Air Corps pilot during World War I. He later worked for the U.S. Post Office, flying air mail starting in 1920, but was grounded in 1921 for failing to promptly report a forced landing, resulting in delay to the mail.

Lanteen sold a comprehensive line of products, including contraceptive jellies, douches, tampons and suppositories.

Riddlesbarger commissioned Phoenix architect Edward C. Morgan to design the Pueblo Revival house and guest house, and the interior was decorated by designer and sculptor Raymond Phillips Sanderson.

He had lost a substantial judgment in tax court over Lanteen's purchase of the ranch lands and subsequent payment of the ranch to him as a dividend. and left the United States shortly thereafter. that had been accompanied by allegations of coercion, but further appeals continued into 1952, reaching the Illinois Supreme Court. Rufus had two daughters with Fay.
