It is commonly accepted that it wasn't until 1974 at a Western Bagel in Woodland Hills, California, that 17-year-old store clerk Bruce Treitman created what is now known as the pizza bagel: a flattened bagel with marinara sauce and mozzarella cheese.
In early 2014, Katz Bagel Bakery in Chelsea, Massachusetts made claim that Harry Katz invented a variation of this pizza bagel in 1970. Unlike traditional pizza bagels, Katz' version is similar to a miniature pizza. Katz uses bagel dough without the hole, topped with cheese and tomato sauce.
There has been a claim that Anthony DeMauro invented the pizza bagel in 1959 at Amster's Bagel Bakery (now closed) in South Euclid, Ohio. However, it wasn't until May 26, 1970 when Amster Pizza Bagel, Inc. submitted registration for Pizza Bagels to the US Copyright Office. On October 1, 1970, Amster Pizza Bagel, Inc. registered for a product that contains 6 frozen pizza bagels in folding cartons with a net weight of 11 ounces.
