Kroll Map Company (1911 - Present) is a Seattle-based map company. Founded in 1911 when Carl Kroll acquired both Anderson Map Company and Washington Map and Blueprint Company, both of which had been in business since the 1870s. From its inception, Kroll Map Company has ‘focused on mapping for real estate and local government, custom mapping, and the publication of numerous general mapping products.’ Carl Kroll sold the company to John Loacker, his close friend and employee, in 1920. Loacker maintained the feel of a family business by working with his some Waldemar. In 1999 Kroll Map Company and Metsker Maps of Seattle formed a partnership of ‘two historic Seattle businesses.’
