Jump to: navigation, search

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.[1] Founded in the late 1940s, the business was sold in 1983 to the photo distributor Brandess Brothers[1] They later acquired Aetna to form BKA (Brandess Kalt Aetna)—which after 2010 merged to form OmegaBrandess who (as of 2022) still exist.[2]

After the deaths of the Outcalts an endowment was established in their names to support UC Santa Cruz's special collections in photography.[3]
