In the United States, The Ritz-Carlton Investing Company was established by Albert Keller who bought and franchised the name. In the early 1900s, several hotels were known as The Ritz-Carlton, in places such as Boston, Philadelphia, Pittsburgh, Atlantic City and Boca Raton. However, by 1940 none of the hotels were operating except The Ritz-Carlton, Boston. The hotel embodies the finest luxury experience, Yankee ingenuity and Boston social sensibilities. The standards of service, dining and facilities of this Boston landmark served as a benchmark for all future Ritz-Carlton hotels and resorts worldwide.
