Born Florence Annie Bridgwood in Hamilton, Ontario, she was youngest of three children of George Bridgwood, an English-born carriage builder and Charlotte "Lotta" Bridgwood (nee Dunn), a vaudeville actress. Charlotte Bridgwood had emigrated to Canada from Ireland after the Great Famine with her family as a child. She was known professionally as Lotta Lawrence and was the leading lady and director of the Lawrence Dramatic Company. At the age of three, Lawrence made her debut onstage with her mother in a song and dance routine.
Also at Vitagraph was a young actor, Harry Solter, who was looking for "a young, beautiful equestrian girl" to star in a film to be produced by the Biograph Studios under the direction of D.W. Griffith. Griffith, the most prominent producer-director at Biograph Studios, had noticed the beautiful blonde-haired woman in one of Vitagraph's films. Because the film's actors received no mention, Griffith had to make discreet inquiries to learn she was Florence Lawrence and to arrange a meeting. Griffith had intended to give the part to Biograph's leading lady, Florence Turner, but Lawrence managed to convince Solter and Griffith that she was the best suited for the starring role in The Girl and the Outlaw. With the Vitagraph Company, she had been earning $20 a week, working also as a costume seamstress over and above acting. Griffith offered her a job, acting only, for $25 a week. After her success in this role, she appeared as a society belle in Betrayed by a Handprint and as an Indian in The Red Girl. In total, she had parts in most of the 60 films directed by Griffith in 1908. Toward the end of 1908 Lawrence married Harry Solter. Lawrence gained much popularity, but because her name was never publicized, fans began writing the studio asking for it. Even after she had gained wide recognition, particularly after starring in the highly successful Resurrection, Biograph Studios refused to publicly announce her name and fans simply called her "The Biograph Girl". During cinema's formative years, silent screen actors were not named, because studio owners feared that fame might lead to demands for higher wages. She continued to work for Biograph in 1909. Her demand to be paid by the week rather than daily was met, and she received double the normal rate. She achieved great popularity in the "Jones" series, filmdom's first comedy series, in which she played Mrs. Jones in around a dozen films. More popular still were the dramatic love stories in which she co-starred with John R. Cumpson, as Mr. Jones, and Arthur Johnson. The two played husband and wife in The Ingrate, and the adulterous lovers in Resurrection. Lawrence and Solter began to look elsewhere for work, writing to the Essanay Company to offer their services as leading lady and director. Rather than accepting this offer, however, Essanay reported the offer to Biograph's head office, and they were promptly fired.

What did she wo while at Biograph?

Lawrence managed to convince Solter and Griffith that she was the best suited for the starring role in The Girl and the Outlaw.

Hedy Lamarr (; born Hedwig Eva Maria Kiesler, November 9, 1914 - January 19, 2000) was an Austrian-born American film actress and inventor. At the beginning of World War II, Lamarr and composer George Antheil developed a radio guidance system for Allied torpedoes, which used spread spectrum and frequency hopping technology to defeat the threat of jamming by the Axis powers. Although the US Navy did not adopt the technology until the 1960s, the principles of their work are arguably incorporated into Bluetooth technology, and are similar to methods used in legacy versions of CDMA and Wi-Fi.
Lamarr was born Hedwig Eva Maria Kiesler in 1914 in Vienna, Austria-Hungary, the only child of Gertrud "Trude" Kiesler (nee Lichtwitz; 1894-1977) and Emil Kiesler (1880-1935). Her father was born to a Jewish family in Lemberg (now Lviv in Ukraine) and was a successful bank director. Her mother Gertrud was a pianist and Budapest native who came from an upper-class Jewish family; she had converted from Judaism to Catholicism and was described as a "practicing Christian", who raised her daughter as a Christian. Lamarr helped get her mother out of Austria (then under Nazi domination) and to the United States, and she later became an American citizen. Gertrud Kiesler put "Hebrew" as her race on her petition for naturalization as an American citizen. In the late 1920s, Lamarr was discovered as an actress and brought to Berlin by producer Max Reinhardt. Following her training in the theater, she returned to Vienna to work in the film industry, first as a script girl, and soon as an actress. In early 1933, at age 18, she starred in Gustav Machaty's film, Ecstasy (Ekstase in German, Extase in Czech). Her role was that of a neglected young wife married to an indifferent older man. The film became both celebrated and notorious for showing Lamarr's face in the throes of orgasm as well as close-up and brief nude scenes, a result of her being "duped" by the director and producer, who used high-power telephoto lenses. Although she was dismayed and now disillusioned about taking other roles, the film gained world recognition after winning an award in Rome. Throughout Europe, the film was considered an artistic work, while in America, it was considered overly sexual and received negative publicity, especially among women's groups. It was banned there and in Germany. She went on to play a number of stage roles, including a starring one in Sissy, a play about Austrian royalty produced in Vienna, which won accolades from critics. Admirers sent roses to her dressing room and tried to get backstage to meet her. She sent most of them away, including a man who was more insistent, Friedrich Mandl. He became obsessed with getting to know her. She fell for his charming and fascinating personality, partly due to his immense financial status. Her parents, both of Jewish descent, did not approve, due to Mandl's ties to Mussolini, and later, Hitler, but could not stop the headstrong Hedy.

Was any film her big break?
