Margot Lander was born in 1910 in Copenhagen, Denmark. She studied at the Royal Danish Ballet School from 1917 and joined the company in 1928. She became principal in 1933 and was the first ballerina in Denmark to be given the title prima ballerina (first solo dancer) in 1942. She was the most important Danish ballerina of the first half of the 20th century and had exceptional personality and grace. She created roles in many of Harald Lander's (her husband from 1932 to 1942) ballets as well as dancing the Bournonville repertoire. Other of her greatest roles were in Coppelia and Swan Lake. She retired in 1950.
