Isabelle Eberhardt (17 February 1877 – 21 October 1904) was a Swiss explorer and author. As a teenager, Eberhardt, educated in Switzerland by her father, published short stories under a male pseudonym. She became interested in North Africa, and was considered a proficient writer on the subject despite learning about the region only through correspondence. After an invitation from photographer Louis David, Eberhardt moved to Algeria in May 1897. She dressed as a man and converted to Islam, eventually adopting the name Si Mahmoud Saadi. Eberhardt's unorthodox behaviour made her an outcast among European settlers in Algeria and the French administration.
