Henrietta Vansittart

Due to limitations with source data it is hard to verify, but it is written in the National Archives that Henrietta likely demonstrated her propeller design to naval engineers. The extent of official recognition and adoption of her propeller by the Royal Navy remains a topic for further research.

Henrietta's contributions to naval engineering, while somewhat obscure for a period, have gained increased recognition in recent years. Historians of science and technology are re-evaluating her role as a female inventor in the 19th century. Further research into contemporary accounts of her invention will illuminate the appreciation and the criticisms that accompanied her achievement at the time.
