'One of Boston's luxury hotels, opened by innovative hostellier Harvey Parker, the Parker House has been operating on this site since 1856. Parker introduced the European plan, started the practice of serving meals continuously, and coined the word scrod, the fresh white fish catch of the day. The famous Parker Roll and the Boston Cream Pie originated here.
'Among the illustrious patrons of the Parker House were Charles Dickens, Ulysses S. Grant and John F. Kennedy. The members of The Saturday Club, a group of leading 19th century authors including Emerson, Lowell and Longfellow, gathered here.'
