Ralph Baggaley (December 26, 1846 – September 23, 1915) was an American businessman and financier who engaged in multiple business ventures throughout his career, most notably in his role as vice-president of the Westinghouse Air Brake Company.

Ralph Baggaley was born to William and Elizabeth (nee Blair) Bagaley[a] on December 26, 1846 in Allegheny City, Pennsylvania.

[2] During the beginning of the American Civil War, Baggaley was sent to Dresden, Germany where he attended a private school.

[3] In 1868, he met and began a relationship with George Westinghouse who had recently invented the railway air brake for train cars.

By now, Baggaley's foundry, one of the largest in the city, allowed him to financially back Westinghouse's invention and create a prototype for testing.
