Frohman now starred Miss Doro in the stage adaptation of William J. Locke's charming story, "The Morals of Marcus." She became one of his pet protegees. With her, as with the other young women, he delighted to nurse talent. He conducted their rehearsals with a view of developing all their resources, and to show every facet of their temperaments. Failure never daunted him so long as he had confidence in his ward. This was especially the case with Miss Doro, who was unfortunate in a long string of unsuccessful plays. Frohman's faith in her, however, was at last justified, when she played _Dora_ in Sardou's great play, "Diplomacy," with brilliant success a year in London and later in New York. * * * With the exception of Maude Adams and Ann Murdock, no Frohman star had so swift or spectacular a rise as Billie Burke. Her story is one of the real romances of the Frohman star-making. [Illustration: _MARIE DORO_] Billie Burke was the daughter of a humble circus clown in America. From him she probably inherited her mimetic gifts. At the beginning of her career she had obscure parts in American musical pieces. It was in London, however, that she first came under the observation of Charles. She had graduated from the chorus to a part in Edna May's great success, "The School Girl." She had a song called "Put Me in My Little Canoe," which made a great hit. Frohman became so much interested that he thought of sending Miss Burke to America in the piece. He transferred the song to Miss May, which left Miss Burke with scarcely any opportunity. Subsequently she was put in "The Belle of Mayfair," and afterward replaced Miss May when she retired. Louis N. Parker saw her in this piece and agreed with Frohman that the girl had possibilities as a serious actress. She was cast for her first dramatic part in "The Honorable George," the play he was then producing in London. When Michael Morton adapted a very beguiling French play called "My Wife," Frohman saw that here was Miss Burke's opportunity for America. He secured her release from the Gattis, who controlled her English appearances, and made her John Drew's leading woman. She met his confidence by adapting herself to the role with great brilliancy and effect. Indeed, with Miss Burke, Frohman introduced a distinct and piquant reddish-blond type of beauty to the American stage. It became known as the "Billie Burke type." Realizing this, Frohman was very careful to adapt her personal appearance, humor, and temperament to her plays. He literally had plays written about her peculiar gifts.
