A gifted journalist with a deep love of the theatre, Harriet Quimby first made a name for herself as a writer at Leslie's Illustrated Weekly. Primarily a writer of feature articles and stage reviews, Quimby also took photos for the publication of her many journeys around the world. Quimby even found success in the world of cinema. Quimby's old theater friend, D. W. Griffith, made several of her scripts into films, making Quimby one of the first female screenwriters.

Quimby was a successful writer at “Leslie’s Illustrated Weekly” when she learned to fly.

In October of 1910, Quimby met Matilde and John Moisant at an aviation exhibition at the Belmont Park International Aviation Tournament. John and his brother, Alfred, ran an aviation school. Since the Wright Brothers did not teach women, Quimby convinced Alfred to teach her and his sister, Matilde, how to fly. Harriet quickly excelled in her new ambition, becoming the first licensed female pilot in the U. S. With her friend, Matilde Moisant, Quimby began touring with the Moisant International Aviators and performing at flying exhibitions. Understanding the power of drama, Quimby created a look for herself which became her trademark - a purple satin flying suit with a hood. With her tall, elegant looks, she instantly caught the public's imagination. Harriet chronicled her adventures in articles for Leslie's Weekly, sharing with the public the exhilaration of flying.

Ever seeking new adventures, Quimby set out to become the first woman to cross the English Channel. In March of 1912, Quimby set sail for England with a letter of introduction to Louis Blériot. Quimby managed to convince Blériot to lend her a 50-horsepower monoplane for her attempt. While Blériot agreed to the arrangement, most everyone around her was convinced she would fail. Even her friend and instructor, Gustav Hamel, offered to disguise himself in her purple suit, fly the plane in her place, and then secretly switch places with her on the French shores. But Quimby refused.

Quimby’s flair for the theatrical led her to design her trademark purple flying suit.

On April 16 she departed for France in a plane she had never flown before and a compass she had just learned how to use. Despite poor visibility and fog, Quimby landed 59 minutes later near Hardelot, France. Upon landing, Quimby was greeted with shouts of adulation by a cheering crowd and was hoisted upon the shoulders of local residents. Quimby, however, would not receive the same worldwide acclaim as her male counterpart, Louis Blériot. The Titanic had sunk just days earlier, casting a large shadow over Quimby's achievement.

Quimby's notoriety did draw large crowds at public flying exhibitions. On July 16th, 1912 she flew at the Third Annual Boston Aviation Meet near Quincy, Massachusetts for the hefty sum of $100,000. In her gleaming new Blériot monoplane, Quimby flew out over Dorchester Bay with the event's organizer, William A. P. Willard. As they were returning, the plane violently pitched forward, Harriet lost control, and Willard was ejected from his seat. Seconds later, Harriet was also thrown out. Both fell to their deaths in front of the entire crowd. Quimby, who had written about safety precautions in flying, was not wearing a safety belt at the time of the accident.

Harriet left behind a legacy, not just as a pilot, but as a woman ahead of her time. Even though she was not a self-proclaimed suffragette, her independence and sense of adventure inspired many women, and helped to pave the way for other female pilots.
