Dorothy Guyott, better known as Dotty and the author of the postcards and letters from the 1929 road trip, was born in 1906 in Massachusetts. She moved to the Bridgeport, Connecticut area with her father Frank Guyott after the death of her mother, Hattie. Her paternal grandparents were from the Bridgeport area. Frank worked as a toolmaker at the Bridgeport Metal Goods Company. She worked as a stenographer for at least five years before the three-month-long road trip. She celebrated her 23rd birthday on August 31, 1929, the day before leaving on the trip.
