Beacon Hill is a prime time period drama series which aired on CBS in 1975. Set after World War I in Boston's Beacon Hill area, the show was conceived as an Americanized version of the popular British series Upstairs, Downstairs (1971–1975) and focused on the wealthy Irish-American Lassiter family and their Irish immigrant servants, who reside together on Louisburg Square.^[1][2]

The show was produced by Jacqueline Babbin^[1] and Beryl Vertue, the former literary agent of Upstairs, Downstairs co-creator Jean Marsh.^[3][4]

The first episode cost $900,000 to produce, and the music was composed by Marvin Hamlisch.^[1] Christopher Schemering of The Soap Opera Encyclopedia called Beacon Hill "the most touted prime-time soap since the Lana Turner-George Hamilton debacle The Survivors".^[1]

The series premiered on August 25, 1975, with an "impressive audience" of "43% of people watching TV" that evening, but it could not sustain those ratings.^[1] Schemering wrote that "the overly large cast and fragmented stories did not allow the audience to get its bearings."^[1] The show was cancelled after 11 weeks (two further episodes remained unaired) with its last episode airing on November 4, 1975.^[1]

The show starred Stephen Elliott as patriarch Benjamin Lassiter, a self-made businessman and éminence grise at Boston City Hall, and Nancy Marchand as his wife Mary, an elegant society woman from a wealthy family. They have five children; eldest daughter Maude (Maeve McGuire), who is married to yachting enthusiast Richard Palmer (Edward Herrmann); middle daughter Emily (DeAnn Mears), who is married to stockbroker Trevor Bullock (Roy Cooper) and is the mother of the spoilt Betsy (Linda Purl); "plain jane" Rosamond (Kitty Winn), who helps out the family business; bohemian Fawn (Kathryn Walker), who is having an affair with her Italian piano teacher Giorgio Bellonci (Michael Nouri); and Robert, the Lassiters’ only son, who has returned from France after losing an arm in World War I.

The servants consist of Arthur Hacker (George Rose), the family butler; his wife Emmeline (Beatrice Straight), the head housekeeper; his niece Maureen Mahaffey (Susan Blanchard), who works as a maid; his nephew Brian Mallory (Paul Ryan Rudd), the chauffeur who is having an affair with Rosamond; former chauffeur Harry Emmet (Barry Snider); footman Terence O'Hara (David Rounds); cook William Piper (Richard Ward) and his son Grant (Don Blakely); Marilyn Gardiner (Holland Taylor), Mary's personal assistant and secretary; and maids Eleanor (Sydney Swire) and Kate (Lisa Pelican).
