Barton's Candy Corporation

"[12] Klein's family developed some of its expertise in an Austrian company named Altmann & Kühne,[13] much of which relocated from pre-World War II Europe to the United States.

[6] Part of the company's 1950s[15] and 1960s[16][17] growth[3] was due to competitions in Jewish schools among classes, competing for prizes for selling the most Barton's products.

"[1] It also helped that Barton's refused to water down the "mouth feel of chocolate" even as other companies were incorporating the use of synthetic ingredients in their products.

"[19] The Atlantic magazine wrote in 2009 that Barton's initially "rejected OU certification" but yielded when faced with competition from Barricini.

[27] Former 2-term Congressman Herbert Tenzer was instrumental in helping the former Barton's Bonbonnieres expand,[6] and served as chairman of the board of directors for two decades.
