Which of the following was the first major female American silent film director?

The first major female American silent film director is recognized as Lois Weber. She made significant contributions to the film industry in the early 20th century and was one of the first women to write, produce, and direct films. Weber gained prominence for her innovative storytelling and technical skills, often tackling socially relevant issues such as women's rights and morality in her work.

Her approach to filmmaking went beyond mere entertainment, as she used the medium to challenge societal norms and depict the complexities of contemporary life. Rather than simply being an actress or a minor contributor in a male-dominated industry, Weber emerged as a leading figure in early cinema, directing numerous films that were well-received and commercially successful.

While other filmmakers like Alice Guy Blaché and Dorothy Arzner also made notable contributions, it is Weber who stands out as the first to achieve major recognition as a director within the American film landscape during the silent era. This distinction highlights her role in paving the way for future generations of female filmmakers.
