The Jeffery brand of automobiles were manufactured by the Thomas B. Jeffery Company in Kenosha, Wisconsin.
History
The company was founded by Charles T. Jeffery and Thomas B. Jeffery, and sold under the brand name Rambler between 1902 and 1913.
On the death of the founder, Thomas Jeffery in 1910, his son Charles took over the business. In 1915, Charles T. Jeffery, changed the automotive branding from Rambler to Jeffery to honor the founder, his father, Thomas B. Jeffery.
Production continued until 1917 when it was sold to Charles W. Nash, former president of General Motors, and formed the foundation of the Nash Motors Company.
Nash Motors went on to become Nash-Kelvinator Corporation, in 1954 merging with Hudson to form American Motors Corporation (AMC), finally bought out by Chrysler in 1987 and becoming the Jeep-Eagle Division of Chrysler.
