History: |
Granco Products, Inc., 36-17 20th Avenue, Long Island City, New York:
The book "Industrial research laboratories of the United States" by John H. Gribbin lists the company on page 227 of the Eleventh Edition. The information was collected from November 1959 to March 1960. The address 36-17, 20th Av. Long Island City, N.Y. is listed in "How to apply for FCC license" which might have been published before 1960. Entry 1704: Granco Products, Inc., 83-30 Kew Gardens Rd., Kew Gardens, N.Y. President: Henry Fogel. Research staff: Seymour Napolin, Executive Vice President and research director; Mark Harwood, Chief Mechanical Engineer; Walter Liwinski, Chief Electrical Engineer; engineers: 5 electronics, 2 mechanical, 5 technicians, 2 auxiliaries. Research on: FM, UHF, receivers and tuners; stereohonics and multiplexing: high fidelity: MF car receivers: electronic air purifiers. Seymour Napolin was born November 2, 1913. According to his doughter, Lee Chinalai, Seymour Napolin was the main founder of Granco Products Inc. One of his engineers was Leopold Harwood and presumably Henry Fogel was was responsible for the business end of Granco. He hadn't renewed the insurance which is why the fire from ca. 1963 ended the company. Seymour Napolin died May 6, 1993 in Westbury, NY, USA. He was son of Jacob Napolin and Rose Einhorn. He was father of Lee Chinalai and James Napolin. The first evidence from schematics we have for Granco is SAMS set 217, folder 6 from October 1953 for a model CTU, followed in 1954 for model LCU, 1955 for MTU, 610 and 720. Beitman shows model 750 in 1957 but SAMS lists it already in 1956. Both publish for models 601 and 701 in 1959. There are 52 hits for Granco. There are patents listed for Seymour Napolin like the number 2,626,313 from Jan. 20, 1953 for "Apparatus for determinging time intervals" or "High frequency capacitors" from July 4, 1961 with number 2,990,606, filed Oct. 27, 1954. Patent 3662235 fro "Co-Axial tuning capacitor devices", filed 12/08/1970 for Melsey. After the fire, Seymour Napolin started his new company, called Melsey Corporation (see also "Electronics world" volume 83 from 1970) to use his over a dozen patents to develop and manufacture VHF and UHF oscillators and a grid-dip meter. Melsey is not mentioned in SAMS Photofacts up to 1974, but there are patents listed. |
