meet the warner brothers and the warner sister, dot

Tinkerers Orville and Wilbur Wright had a sister named Katherine, a teacher, suffragan, and alumna of Oberlin College (the only graduate in the family), who very substantially contributed to their (while not seminal—more here and here) important and pioneering demonstrations of powered-flight.
Though there’s no clear documentation whether the unsung Wright had wished herself to be an aviatrix or helped with the design, there is testament to her relatively unacknow- ledged work behind the scenes that included running the brothers’ bicycle shop while they were away experimenting (with no backers, their only source of funding for their trials) better than they had done themselves and acting as their unwavering publicity agent and tour manager, encouraging them to persevere against a doubting public.
