Miller Outcalt was an Ohio-born entrepreneur who, together with his wife Bunny, became a successful photographic supplier based in Santa Monica (CA), trading under the KALT and Milo / Mil-O brands. Founded in the late 1940s, the business was sold in 1983 to the photo distributor Brandess Brothers They later acquired Aetna to form BKA (Brandess Kalt Aetna)—which after 2010 merged to form OmegaBrandess who (as of 2022) still exist.
After the deaths of the Outcalts an endowment was established in their names to support UC Santa Cruz's special collections in photography.
