The real history of Pop-Tarts that inspired the Jerry Seinfeld Netflix movie Unfrosted.

Post played an important role in co-creating the iconic Pop-Tarts brand in 1964, when Pop-Tarts debuted.

Post, of Grand Rapids, Michigan, got his start as a 16-year-old truck washer at a biscuit plant.

When he started out, Post said he and fellow truck washers were “poor as church mice.” But he worked his way up to plant manager when the people from Kellogg’s came to him with a concept.

There are now more than 20 flavors of the sweet-filled treat.

Post died Saturday, according to a family obituary which provided no details on his death but says he was raised in Grand Rapids as “one of seven children of Dutch immigrants” and had retired at age 56 as a senior vice president with Keebler Company and settled in Glen Arbor, Michigan.

William Post died at the age of 96 on Saturday. He was a co-creator of Pop-Tarts.

The snack quickly became a popular treat for many in the U.S., including Post’s kids, who were among the first taste testers.
