Ingebjørg Lillemor Rachlew (née Enger; 7 January 1902 – 14 May 1983) was a Norwegian Antarctic explorer. In 1937, she was one of four Norwegian women - Rachlew, Ingrid Christensen, Augusta Sofie Christensen, and Solveig Widerøe - who were the first women to set foot on the Antarctic mainland. The Four Ladies Bank, a submarine bank north of Prydz Bay was named after them.[1][2]
On an earlier voyage to Antarctica, Rachlew took photographs which were published in 1934. Some sections from her diary were preserved and these are the earliest examples of a woman's writing about her travels in Antarctica.
