Ella Shields was born in Baltimore, Maryland, in 1879. Her true surname appears to have been Buscher. She was educated at South Bend, Indiana. It is not certain when she adopted the stage name Shields. "Ella" might also have been a stage name. She began her career in 1898 doing a vaudeville song-and-dance act with her sisters. In 1904 a talent scout lured Shields to London, where she was billed as the "Southern Nightingale." In 1906 she married the songwriter William Joseph Hargreaves in Lambeth, London. In 1910 she appeared at the opening night of the London Palladium. It was at this time that she became a male impersonator. The story goes that one night in 1910 Shields was attending a party at which music-hall performers did their acts for one another. Half of a two-man musical act was out sick, and Shields put on trousers to fill in for him. This impromptu turn in trousers proved to be the turning point of her career and she rarely wore dresses on stage again.
‘With wavy auburn hair and dressed as a young man in evening dress, nervously fingering his white tie, she made a very charming and gay figure...and though she adopted the tattered clothes and worn top hat of the traditional “broken down swell” act she did so with a difference, making of what might have been ordinary broad comedy something delicate and, in its way, almost moving.’
In 1915 her song-writing husband, William Hargreaves, wrote "Burlington Bertie from Bow", a comic ditty about a penniless Londoner who affects the manner of a well-heeled gentleman. It was a parody of an earlier song, simply called Burlington Bertie, written by Harry B. Norris and made famous by Vesta Tilley. Shields sang the song, dressed up in slightly battered top hat and tails, in the role of Burlington Bertie 'himself'. She toured the world in this role, including appearances at Baltimore's now-demolished Maryland Theatre in 1924 and '26. The persona of Bertie haunted the rest of her life and she was known as Bertie as much as Ella. She and Hargreaves had separated in 1916 and they divorced in 1923. The Depression brought difficult times for many entertainers, and Shields announced her retirement in 1929. She spent time working at a Macy's jewellery counter in New York. After a period of performing in obscurity, a music-hall reunion show called Thanks for the Memory put "Bertie" back in the spotlight. This show ran throughout England for over three years from 1947–51. Ella worked with many stars over the years, including a very young Julie Andrews in the late 1940s with whom she shared the same bill of a Royal Command Performance. Julie Andrews pays tribute to Ella Shields in her own one woman show and has recorded Shields' famous song "Burlington Bertie from Bow". It is possible that Julie Andrews used Ella Shields as her role model for 'Victor' in the film and stage musical Victor/Victoria. In August 1952, a septuagenarian Shields performed in northern England. Her death was dramatic. Singing her trademark song, in what would be her final show, instead of the traditional opening lines 'I'm Burlington Bertie', she began with 'I was Burlington Bertie'. After finishing the song she collapsed on stage and died three days later, without regaining consciousness, at Lancaster in Lancashire, on August 5, 1952. Her body was cremated at Golders Green Crematorium in London. In the cemetery courtyard she shares a memorial plaque with music hall star Nellie Wallace. Her repertoire of songs was related to her male-impersonation act, which was often in military attire. They included:
