Gloag was born in London, the daughter of Scottish parents from
Perthshire. Her early studies were made at
St. John's Wood Art School, and she later studied at the
Slade School of Fine Art. Ill health compelled her to put aside plans for regular study and she entered the studio of M.W. Ridley's for private instruction, following that with work at the
South Kensington Museum. After further study with
Raphaël Collin in Paris, she returned to London and soon had her work accepted at the
Royal Academy of Arts, where she exhibited a total of 19 works. She made several designs for the stained-glass artist
Mary Lowndes. Suffering from health problems throughout her life, she died in London on 5 January 1917, aged 51. Her work was posthumously featured in an exhibition at the
Grafton Galleries, London. ==References==
