Hammond Manufacturing traces it's roots back to a small basement shop set-up during
the years of the First World War by Oliver S. Hammond - tool & die maker by
day and amateur inventor by night. (Yep...Fred's dad!!! For those who knew Fred
- famous radio amateur VE3HC) The company became O.S. Hammond & Son
and soon included sons Len, Roy, Ken and Fred. Later Oliver's first "shop"
was a 20 by 30 foot facility behind the family home. The shop was powered by a
boiler that burned just about anything. The steam from the boiler powered a small
steam engine, which turned the main shaft and pulleys. Remember, there was no
electricity service yet! Steam power, human power, light of day or lantern was
a fact of life!
- The company began to build early radio sets, just as the first radio stations
began to spring to life one by one around the United States. Starting out with
a single tube radio (link here to a local 1923 Guelph,
Ontario newspaper article) and progressing to 5 and finally 6 tube models
one of only three known remaining Hammond "Model 12" 5 tube receivers
(built between 1923 -1924).

Our previous years experience put Hammond in the forefront of the manufacture
of magnetic components during World War II for communication transmitters and
very specialized transformers for radar.

Korea and the beginning of the Cold War once again thrust upon the Company significant
volumes of military transformers, especially as a result of the construction of
extensive early warning radar systems across Alaska, Canada and Greenland.
1960's - 1970's
- The prosperous decades of the 60's
and 70's saw the Company expand into an even broader range of specialized and
catalog transformers and cabinetry for the electrical and electronic industries.
It is during this time that the company expands into the U.S. and World markets.
In 1978, Rob and Bill
Hammond acquired control of the company and thereby ensured passage of the business
into the third generation of the Hammond family. The Company was then re-organized
into three separate profit centers for transformers, cabinetry and power supplies.
A Corporate service group was also established for the sales, marketing and distribution
of catalog products.
- Hammond took another step in Corporate evolution by trading its shares on the
Toronto Stock Exchange (TSX)
- (Traded under the symbol HMM.A).
Hammond Manufacturing joins the World Wide Web! A user friendly, low bandwidth,
specifier site is created. Our design theme continues to this day.
