Chances are you have probably played with a gyroscope at some point in your life. More than likely, it was a Chandler gyroscope. For over 70 years the Chandler Company of Indianapolis, Indiana, produced and sold virtually tens of millions of gyroscopes all over the country. In 1982 TEDCO, Inc. purchased the Chandler Company. Since then, the toy line has expanded.
TEDCO was first established as a research & development company by the late Ralph Teetor. Mr. Teetor was a well-known and highly respected inventor who started TEDCO (Teetor Engineering Development Company) as a vehicle to foster his inventions. His most renowned accomplishment is the cruise control on your automobile.
