Ralph R Teetor
(1890-1982) Automotive Pioneer and Lake Wawasee Resident
Ralph Rowe Teetor of Hagerstown, Indiana, only child of John (1860 – 1939) and Kate Rowe Teetor, was surrounded by a huge, supportive family – some 20 households of Teetor families plus 17 uncles & aunts on his mother’s side. An accident in 1896 resulted in Ralph Teetor’s blindness.
- When asked what more he could have done had he been able to see, Ralph replied, “I probably couldn’t have done as much, because I can concentrate & you can’t.”
- A reporter was quoted as saying: “I only wish I could see as much with two good eyes as Ralph does with none.”
- Ralph R. Teetor had an iron-willed perseverance in a world that was reluctant to allow him to be independent.
- Ralph commonly used expressions such as, “Let me see it” or “I think I see the problem.”
Ralph Teetor’s life spanned the entire development of the automobile industry in the U.S., participating in much of its technology.
Pictured in the early 1890s, John Teetor rides a bicycle designed by his younger brother Charlie (C.N.) to be ridden on the railroad tracks for inspection purposes. A similar vehicle hangs in the foyer of John Teetor’s great-grandchildren’s home in South Park, Lake Wawasee, Indiana.
This bicycle design led to the 1890’s incorporation of the Railway Cycle Manufacturing Company in Hagerstown, Indiana, by the five Teetor brothers – Charles N., John (Ralph’s father), Henry, Frank and Joe – plus Charles Hartley and his father, John; and Henry Keagy. Soon the vehicles were being shipped all over the world.
Piston rings are the key to effective combustion, thus leading to more powerful engines. In 1926, “Perfect Circle” became the company name, merging with the General Piston Ring Company in Tipton under the management of Daniel C. “Dan” Teetor. Ralph pointed out, “if a circle isn’t perfect, it isn’t a circle.”
Perfect Circle piston rings were first used in the Indy 500 winning cars as early as 1922; Ralph was chief steward in 1937.
Ralph was familiar with the design and production of practically every part of the automobile engine, making him a favorite consultant for race car builders.
In 1936, Ralph Teetor was elected president of the National Society of Automotive Engineers with safety as his major theme in talks around the country.
Riding with a lot of different drivers led Ralph Teetor to invent one of today’s most popular and useful automotive accessories – cruise control. After World War II, he started working on the concept which drivers embraced by the early 1970s.
The Lake Wawasee Connection

Sargent’s Hotel was built in 1914 on the north shore of Lake Wawasee. Ralph R. Teetor first signed the Sargent’s Hotel Guest Register in July 27, 1915.
Ralph tested his first craft on Lake Wawasee – a 22-foot planning speedboat, probably built from a kit around 1914, powered by four-cylinder Teetor-Hartley engine. Piloted by second cousin Dan Teetor, they drove the boat to speeds exceeding seventy miles an hour, “an insane speed for a boat in those days!”
For one summer, Ralph brought Chris & Jay Smith’s Miss Detroit to Wawasee to see how she would run on the smooth surface of the largest lake in Indiana.
In 1921, seeking a better place to keep his boats, Ralph persuaded his parents (John and Kate Teetor) to purchase a cottage on the south shore (South Park) of Lake Wawasee, the largest natural lake in Indiana. Wawasee is located in northeastern Indiana near Syracuse, a little over 130 miles from Ralph’s hometown of Hagerstown.
In 1931, Ralph & wife Nellie purchased a cottage next door to his parents. It was a wonderful, rambling old frame house first built in 1897. Ralph loved to change and improve the house throughout his lifetime. It continued to be enjoyed by three more generations, until in 2022, maintenance became overwhelming, leading to building a new house on the site. The John Teetor home had previously been replaced when Ralph’s grandchildren needed space to spread out.
Other Teetor families & factory executives followed Ralph to Wawasee, renting, building, or purchasing summer cottages. The days at the lake were carefree vacation getaways.
South Shore Inn on Lake Wawasee, Indiana, was headquarters for many Perfect Circle 500 Mile Race parties for buyers and officials of the company.
During the summer of 1962, Ralph Teetor, Landrum Bolling (president of Earlham College), and Eli Lilly crossed the lake by boat many times as the Lilly and Teetor homes were used to work out a plan for the college to take possession of the William Conner estate, known today as Conner Prairie living history museum.

The Syracuse-Wawasee Historical Museum “sold out” the historic Pickwick theater in uptown Syracuse on Tuesday, July 23, 2024, for the Lake Wawasee Premier of “Blind Logic,” a new documentary about Wawasee’s own Ralph Teetor. Due to the overwhelming response, a second showing of the documentary was held the next evening. Free-will donations benefited the Syracuse-Wawasee Historical Museum. The event was a total community effort in conjunction with the Teetor family!
The documentary follows the extraordinary journey of Ralph Teetor from childhood blindness through his life of fierce determination and distinctive mental vision to become an inventive, insightful leader, and philanthropist. Teetor’s life spanned the entire development of the American automobile industry. He became president of Perfect Circle Piston Ring Corporation in Hagerstown, Indiana, and his modern cruise control invention makes driving much more relaxing.
The Lake Wawasee connection for the Teetor family started at the Sargent Hotel as early as 1915. Seeking a more convenient place to keep their speedboat, it wasn’t long before Ralph’s parents bought a cottage in South Park, beginning over a century of the family summering on Lake Wawasee. His great, great grandchildren still enjoy the property today. Other Teetor families & factory executives followed Ralph to Wawasee. The days at the lake were carefree vacation getaways.
Thanks to Ralph Teetor’s great grandson, Jonathon Meyer, compiling vintage family movies, and to Music Composer Jim Andron (pictured above at a young age on the lake.), the audience was treated to a preview film of Teetor families enjoying Lake Wawasee. The “Blind Logic” documentary credits include three of Dan Teetor’s grandsons who often visited the lake: Writer, Director and Producer Jack Teetor, Photo Editor Daniel Teetor and Music Composer Jim Andron. We even found out that A mural honoring inventor Ralph Teetor won a Fort Wayne artist top prize in the Wayne County Murals Program’s competition, according to a news release.
Fort Wayne artist Chris Catalogna, a relative of lake resident Jane Finch, won top prize in the Wayne County Murals Program’s competition this summer. His larger-than-life painting of Ralph Teetor and his contributions to the Hagerstown community fills the length of The Boot Box, 60 W. Main St.

Perfect Circle, the undisputed world leader in piston ring technology, attributed its success to its talented and loyal employees.
