Early Life
Teetor became blind at age five in an accident, but as a grown man he preferred never to discuss his disability. He graduated from the University of Pennsylvania in 1912.
Teetor's highly developed sense of touch proved helpful in developing a technique for balancing steam turbine rotors used in torpedo-boat destroyers. Dynamic balancing of large components had puzzled others before Teetor solved the problem.

Famous quotes containing the words early and/or life:
“Our instructed vagrancy, which has hardly time to linger by the hedgerows, but runs away early to the tropics, and is at home with palms and banyans—which is nourished on books of travel, and stretches the theatre of its imagination to the Zambesi.”
—George Eliot [Mary Ann (or Marian)
“Toiling,—rejoicing,—sorrowing,
Onward through life he goes;
Each morning sees some task begin,
Each evening sees its close;
Something attempted, something done,
Has earned a night’s repose.”
—Henry Wadsworth Longfellow (1809–1882)
