[1] After her move to London in 1893, Christy found employment initially escorting ladies on rides.
[1] She was noted for her work rehabilitating servicemen after the First World War, promoting riding using a sidesaddle for people with prosthetics.
[1] Christy was one of the foremost writers about horsemanship for women of her time, following Nannie Power O'Donoghue and Alice M.
[4] Her first book, Side-Saddle Riding: A Practical Handbook for Horsewomen, appeared in 1899; it proved popular and further editions came out in 1901 and 1907.
[1][4][6] The historian Erica Munkwitz describes the book as one of the two most important works on riding for women to be published between the wars.
[1] She was also interested in safe and practical riding dress for women, as long skirts posed the danger of getting caught up in the horse's legs or attached to the saddle, again leading to the risk of dragging.
[7] She later wrote that the only type of skirt that did not pose a risk of dragging had its "cloth cut away from beneath the entire seat when in the saddle", and offered to forward the details of tailors making such a garment to horsewomen.
