Born in London in 1837, as Katherine Carr, Kate Gardiner Hastings received her artistic education at the Slade School in London. From 1871 - 1876 she studied with John Poynter and upon the completion of her studies, in 1877, she married Alfred Gardiner Hastings. For the next few years she exhibited regularly showing her work at the Dudley Gallery and the Walker Gallery.

The artist drew a series of portraits of Terry’s family circa 1890 which are now part of the National Trust Collection and held at Terry's former home, Smallhythe Place in Kent (NT/SMA/D/20, 21, 22, and 23). These portray Benjamin and Sarah Terry, (the actress’s mother and father) and her children Edith, the theatre director and activist and Edward Gordon Craig, the theatre designer. The pastel of Sarah Terry (1817-1892) was exhibited at the Summer Exhibition of 1890 at New Gallery, London.

Another red chalk portrait of the actress as Ophelia in Hamlet c. 1878 by the artist is in the collection of the Victoria & Albert Museum (S.1484-2014).
