Sigrid Ida Matilda Kahle (née Nyberg; 18 September 1928 – 31 December 2013) was a Swedish journalist and writer.

[2] In her youth, she was interested in the theatre and after graduating she applied to a drama school, but was not accepted.

Instead, she enrolled at Uppsala university where she studied the history of literary drama.

She travelled to London together with her father in 1946, and stayed with him in the home of the German orientalist Paul E. Kahle who had escaped from Germany with his family in 1938, after they had become targets of Nazi persecution for helping Jewish friends and neighbours.

[3] One of the sons in the family, John Kahle, fell in love with Sigrid Nyberg and the couple corresponded for some time after she had returned to Sweden.
