For over 70 years the Indiana-based Chandler Co., produced and sold millions of gyroscopes. In 1982 TEDCO, Inc. purchased the Company and has since vastly increased toy lines with global sales. TEDCO (Teetor Engineering Development Co) was first established as a research & development company by the late Ralph Teetor (a well-known and highly respected inventor) as a vehicle to foster his inventions. His most renowned accomplishment is cruise control for cars. Mr. Teetor was blinded at an early age, but his lack of sight never hindered his creative genius. He was president of the former Perfect Circle Corp and was inducted posthumously into the Automotive Hall of Fame. Today, TEDCO is owned by Mr. Teetor's daughter and family along with some TEDCO employees. TEDCO now manufactures scientific and educational toys like the TEDCO Gyroscope.
