Gluck (born Hannah Gluckstein; 13 August 1895 – 10 January 1978) was a British painter, who rejected any forename or honorific (such as "Miss" or "Mr"), also using the names Peter and Hig.

Gluck joined the Lamorna artists' colony near Penzance, and was noted for portraits and floral paintings, as well as a new design of picture-frame.

[1] Gluck's father was Joseph Gluckstein, whose brothers Isidore and Montague had founded J. Lyons and Co., a chain of high street tea rooms and a catering empire.

Gluck's American-born mother, Francesca Halle, was training to be an opera singer when she met her husband to be, a childless widower twice her age; they married six weeks after meeting.

In October 1924, Gluck first had a solo exhibition, of fifty-six paintings, at the Dorien Leigh Galleries in South Kensington, London.

[1] During 1925 Gluck painted a series of works depicting theatre scenes, which formed part of the 1926 Stage and Country exhibition at the Fine Art Society in London.

[1] Gluck ended the relationship with Spry and held a bonfire of personal letters, diaries and paintings at Bolton House.

[9] According to Gluck's biographer Diana Souhami, "They sat together in the third row and felt the intensity of the music fused them both into one person and matched their love."

[1] In 1945, Gluck sold Bolton House but retained the studio, continuing to use it for a few years, eventually selling it in 1949 to artist and author Ithell Colquhoun.

In 1977, Gluck donated 57 items, including clothing, accessories and pieces relating to the time spent in Tunisia, to the Brighton Museum & Art Gallery.

[1] In 1982, Virago Press chose Medallion, Gluck's self-portrait with Nesta Obermer, as the cover art for its mass-market paperback edition of The Well of Loneliness.

[1][14] July-August 1998 saw a "a small but beautifully curated exhibition of some of the most memorable paintings" by Gluck, in Bexhill-on-Sea, at the De La Warr Pavilion.

[15] In 2017-2018, the painter was the subject of an exhibition at the Brighton Museum & Art Gallery, an accompanying book of the same title (Gluck: Art and Identity, Yale University Press), and an academic event at the London College of Fashion featuring the authors and curators Martin Pel, Dr Jeffrey Horsley and Prof Amy de la Haye.

[16] Gluck's painting Flora's Cloak (circa 1923) was acquired by Tate in 2019 "with funds provided by the Denise Coates Foundation on the occasion of the 2018 centenary of women gaining the right to vote in Britain".
