Career
Lehmann was the daughter of Anne (née Kirkwood) and Robert Chambers, the Scottish writer and publisher. Their daughter Liza wrote in her memoirs:
My mother certainly had extraordinary gifts, but suffered all her life from quite abnormally developed diffidence. As a girl, she was so musical that her father declared she did not require lessons! The few people who heard her sing have never forgotten her quite peculiar charm.
She had a wonderful ear, the gift known as "absolute pitch," and could transpose easily at sight.
She wrote some beautiful music, notably an operatic setting of a Goethe libretto. But the same diffidence and exaggerated, almost morbid self-criticism, led her to destroy most of her compositions, including with them many of her best.
