This advertisement from Thordarson is from one of my oldest editions of the American
Radio Relay League's QST magazine - December 1929.
Thordarson Electric Manufacturing
Company was founded in Chicago, Illinois, by Chester H. Thordarson in 1895.
He was the first producer of industrial and commercial transformers. They are still
in business today. Thordarson patented more than 30 inventions for transformer design
and manufacturing back in its early days, including the still most popular form
of laminations, the scrapless "E and I." Many discussions are available on various
transformer lamination configurations, including the very common "E and I" types.
