TAL comes out of Katha, a non-profit publisher and education organisation in Delhi. It was created by Katha's founder, Geeta Dharmarajan, who received the Padma Shri for her work in literature and education.

Geeta Dharmarajan founded Katha in 1988 and has spent the years since working on children's reading and on the method the books use. She wrote or edited much of the material, chose the stories, and shaped how they're taught. TAL is the current form of that work, gathered into eight books.
