De Hammond Archieven 1

Op een paar (zich in in Amerika bevindende) plekken, liggen een paar enorme "Hammond-Archieven", met een ware schat aan materiaal, wat voor onze  Hammond-Encyclopedie , natuurlijk een ware "Grot van Ali-Babba" zou zijn!

Het éérste bevindt zich in het hoofdkantoor van HammondSuzuki in de VS, hieronder aan ons getoond door Dennis Capiga,de huidige Excecutive Vice President van Hammond-Suzuki ( 2013).


(de kasten rechts zijn voor micro-fiches):


Hier bevinden zich o.a. alle oude schetstekeningen (hieronder die van één van de printplaten) :

Het hele archief is indertijd óók nog op microfishe gezet, wat het naslaan van data vergemakkelijkt.

Hieronder nog even de baas zelf achter een Hammond:

Historical sketch:

Laurens Hammond (1895-1973) was responsible for numerous inventions, including an alternating current electric clock (patented in 1929), a synchronous electric motor (patented in 1932), the first electric organ (patented in 1934), the first all-electronic organ (patented in 1939), and the first spinet electronic organ for homes (patented in 1949). Altogether, Hammond was granted about 280 patents from 1912 until his death in 1973.

The company founded by Laurens Hammond and his associates was incorporated in 1928 as the Hammond Clock Company. It became the Hammond Instrument Company in 1937, after the firm started making electric organs as well as clocks, and then became the Hammond Organ Company in 1953, after the firm stopped making clocks. The Hammond factory was located at 2915 N. Western Av. from ca. 1930 to 1949 and at 4200 W. Diversey Av. from 1949 to 1986, but there were additional plants and offices elsewhere. In 1967, after the Hammond Organ Company acquired the Wells Lamont Corporation, a glove manufacturer, the name of the parent company was changed to the Hammond Corporation, and the Hammond Organ Company became a division of the Hammond Corporation. Wholly or partially owned subsidiaries were established outside the United States to distribute, and in some cases manufacture, Hammond organs. These included Hammond Organ (U.K.), founded in 1964 to handle distribution in the United Kingdom; Hammond Organ Europe, N.V., founded in 1967; Hammond International, Canada, Ltd., founded in 1969; the Nihon-Hammond Limited Company, Osaka, Japan, founded in 1970 in partnership with Sakata Shokai, Ltd., to distribute Hammond organs in the Far East and parts of Europe (later also manufacturing them); and Hammond Organ Australia, PTY Ltd., founded in 1982.

In 1977 The Marmon Group, Inc., owned by the Pritzker family of Chicago, acquired the Hammond Corporation, and the Hammond Organ Company became a division of The Marmon Group. In 1986 The Marmon Group sold the Hammond Organ Company to Hammond Organ Australia, PTY Ltd, then owned by Noel Crabbe of Australia, and manufacturing of Hammond organs was discontinued in Chicago. Tentative plans called for the manufacturing of Hammond organs in Japan.

Description of the collection:

The corporate records relate to Mr. Laurens Hammond (1895-1973) and the company he founded, which was known as the Hammond Clock Company (1928-1937), the Hammond Instrument Company (1937-1953), and finally the Hammond Organ Company (1953-1986). Correspondence, reports, minutes, manufacturing drawings, patents, budgets, and other operating records of the company that founded the industry of small electric organs and helped to popularize organ music for home and small institutional venues.

The corporate records generally are in record cartons: 12 1/2 x 15 1/2 x 10 in.
