In 1923, two Jewish-American brothers — Henry and Helal Hassenfeld — founded Hassenfeld Brothers, a textile remnant company. As the years went by, the company began producing pencil boxes and school supplies. In the 1940s, Hassenfeld Brothers produced doctor and nurse kits, its first toys. Hassenfeld Brothers’ first hit toy was Mr. Potato Head. The toy was an outstanding success.
Hasbro found another smash hit when it produced G.I. Joe. The toy was called an “action figure” because boys didn’t want to play with “dolls.” Hasbro continued its success in 1984 with the release of the first Transformers toys. Hasbro is one of the largest toy makers in the world, second only to the toy giant Mattel. Hasbro is also the publisher of the world’s most popular board game, Monopoly. They are also the producers of dozens of other hit toys, such as the “Easy-Bake Oven”, “Pokemon” and “Play-Doh.”
