CORO INFO by: Anonymous
CORO/COHN AND ROSENBERGER c. 1900-1979
Coro jewelry, Cohn & Rosenberger, was founded in New York by Emanuel Cohn & Carl Rosenberger in 1901/1902 & incorporated in 1913. A factory was established in Providence, RI in 1911.
With offices or plants in New York & Providence; at times they had a presence in Chicago, Los Angeles, San Francisco, Miami, Toronto, England and Mexico. Great Britain mechanical patents have been found in the name of Corocraft from 1961 until 1969, which documents actual production in England (courtesy Mary Walden-Till).
Cohn died in 1910, but the name remained Cohn & Rosenberger. The corporate name "Coro" was adopted in 1943. Rosenberger died in 1957, & his son Gerald, who succeded him, died in 1967.
In 1969 the family sold 51% of the Coro stock to Richton, Intl. Corp., who bought the remaining stock in 1970. Richton also owned the Oscar de la Renta brand. By 1979 all the Coro companies, except the Canadian company, were bankrupt. It was sold to a South American company in 1992 & also went backrupt.
Gene Verri was the head designer and personally responsible for many, many of Coro's famous designs. Adolph Katz signed many of the patents only as a representative of the company. Information confirmed by Ron Verri , Gene's son -- 9/8/05.
Designers for Coro according to Brunialti: Gene Verrecchia [Verri] --1933 to the end of the 1963 (he and his son Ron own Gem-Craft) Charles E. Pauzat--1939-1940's Oscar Frank Placco --1934-1945?
