The summer of 1910 caught in delicate colour...

These charming autochromes were taken between 1910 and 1915. They show Janet and Iris Laing in their parents’ house and garden in Headington, Oxford.

The pictures were taken by the girls’ mother, Etheldreda Laing, an artist and photographer. Etheldreda died in 1960.

In about 1930, Janet became the second wife of Howard Montagu Bulmer de Sales La Terriere.

In 1958, Iris, aged 55, married Sir John Randolph Leslie, 3rd Baronet of Glaslough, becoming Lady Shane Leslie. She died in 1995.

Bury Knowle House is now a library, and the gardens are a park.

The images are now held by the Science Museum, through the Science and Society Library.
