In August 1917, La Badie was at the height of her motion picture success. She had appeared in 185 films since 1909, 32 fewer than
Mary Pickford's 217 films during the same period. Her film
The Woman in White had just been released in July 1917. Her most recent two films, an adaptation of
Edward Everett Hale's short story
The Man Without a Country, and
War and the Woman, were both scheduled to be released on September 9, 1917. Although the Thanhouser Corporation had been struggling since the 1914 death of
Charles J. Hite in an automobile accident, La Badie's career was thriving and had been their saving grace. Less than a month earlier, she had announced that she was leaving Thanhouser. She said that several other film corporations were willing to pick her up on contract immediately. On August 28, 1917, while driving near
Ossining, New York, in the company of her
fiancé, Daniel Carson Goodman, her brakes failed and the vehicle plunged down a hill, overturning at the bottom. She was thrown from the vehicle and suffered serious injuries, including a compound
fracture of the pelvis, while Goodman escaped with only a broken leg. Hospitalized, she clung to life for more than six weeks and seemed to be improving, but suddenly died on October 13 from
sepsis. La Badie was the first major female film star to die while her career was at its peak, and the movie-going public mourned her death. After a large funeral, she was interred in an unmarked grave in the
Green-Wood Cemetery in
Brooklyn, New York. In a deposition in a legal proceeding days before La Badie's death, Marie C. Russ swore in a deposition to have been her biological mother. Obituary notices stated La Badie was survived by her mother, Amanda La Badie, with no mention of her having been adopted. Upon her death, her estate was divided between her parents, Mr. and Mrs. Joseph La Badie. In 2014, Ned Thanhouser, the grandson of Edwin Thanhouser, raised money for a headstone for La Badie, which was installed on April 27 of that year, on what would have been her 126th birthday. ==Selected filmography==
