[3] She began at the bottom of the ladder and according to a writer in 1900, "her advancement was thoroughly legitimate, meaning good hard work with every rung."

In 1894 she acted in support of Olga Nethersole in The Transgressor at Palmer's Theater, 485 Broadway near Broome Street.

Together with Drew she starred in Richard Carvel, a play based on a best-selling novel written by the American novelist Winston Churchill.

Conquest succeeded Isabel Irving as the leading lady of the John Drew Company.

In 1907 Conquest appeared in several shows at Denver's Elitch Theatre, including Leah Kleschna and the play of The Second in Command.

[4] Additional theatrical productions in which Conquest participated are The Girl With The Green Eyes, written by Clyde Fitch, The Money Makers, Man and Superman, Little Brother of the Rich, Wolf, and The Talker.

To acquire proficiency she spent a number of weeks in the factory of Roman Bronze Works in Greenpoint, Brooklyn.

Bertelli, a graduate of the University of Turin, established himself in New York in the decade before he married Conquest.

A daughter, Gigiotta Bertelli, who later married Gabriele D'Annunzio's son Ugo,[5] was the only member of the immediate family present.
