Written by Jez Stewart for his post Staff snapshot – 1946: Part 2:

“Stella studied Commercial Art at the Central School of Arts and Crafts through most of the war thanks to a school scholarship, and was on the verge of being called up for the Land Army when she got a referral to work at H&B through a friend’s cousin. Because the company was working on films for the war effort she could work there rather than be called up, and liked it so much she managed to stay for a few years. She worked as an inbetweener, and enjoyed the atmosphere of the studio – especially Wally – but her true interest was commercial art and she moved on by the late forties and left animation behind.
(Stella was interviewed by Vivien Halas in Martin Pickles c.2010)”
