Braun ET66 Calculator When it originally debuted in 1987, Braun’s iconic ET66 helped elevate the calculator to an everyday personal item.

In addition to signs, Rose documents storefronts, like J. Braun Liquors in New York City. "Julius Braun was a Jewish immigrant who arrived in the United States from Poland with his family in 1921," he writes. "He was only seven years old at the time. City records indicate that the neon signage was installed in 1952.
