The H.B. Reese Candy Company was established in 1923 by H. B. Reese in Hershey, Pennsylvania. The official product name was "Penny Cups" because they could be purchased for one cent. Reese had originally worked at a Hershey dairy farm, and from the start, he used Hershey chocolate in his confections. Reese's Peanut Butter Cups were his most popular candy, leading Reese to eventually discontinue his other lines. Reese died in 1956, passing the company to his six sons, Robert, John, Ed, Ralph, Harry, and Charles Richard Reese. On July 2, 1963, the Reese brothers merged the H. B. Reese Candy Company with the Hershey Chocolate Corporation in a tax-free stock-for-stock merger. In 1969, Reese's Peanut Butter Cups became the Hershey Company's top seller.
