I had the good fortune to work with Elinor Goldschmied in the early 1980s, when she was actively disseminating her ideas about the Treasure Basket in the UK. This collaborative work led to our research into the exploratory play of toddlers (10–20 months) which we named Heuristic Play. The Treasure Basket and Heuristic Play became widely known following the film we made, Heuristic Play with Objects, in 1992 and the publication of the book, People Under Three (Goldschmied and Jackson 1994). Elinor and I collaborated in film-making, training and research until she ‘retired’ at age 90 in the year 2000, but we were friends till her death in 2009.
