William Vetovitz (born in 1928) was the company owner and a bricklayer. He received US Patent 3148432 for the mortar spreader on 15 Sept. 1964. He received US Patent 3799714 on 26 Mar. 1974 for a version called a mortar applicator. The 4-page brochure is not dated, but appears to be from the 1970s. This 1975 book mentions the Mortar Spreader. By that year, Vet-O-Vitz Masonry Systems was making prefabricated brick panels for buildings and retaining walls. One of his best-known projects was for the Vontz Center in Cincinnati, Ohio. The company was in business as recently as 2013, but is now out of business.
