Ian Long is an illustrator who has worked with Pip all of his adult life, drawing, creating and visualising ideas that they have imagined together since the early 1980s. He has been a youth and pastoral worker in Gloucestershire, a primary school teacher in West Sussex and Hampshire, a carer for his father who suffered with Alzheimer's and is now working full-time on books.

Pip Wilson (1939-2023) was a pioneering youth worker, author, and communicator. He ran a youth club and community centre in one of the most deprived areas of London, working with young people, many of whom were caught up in gangs and struggled to articulate their feelings and emotions. During this period, Pip realised the importance of managing his own feelings so that he was in a better position to help others. It was this understanding of emotional intelligence that laid the foundations for what would eventually inspire him to create the "Blob Tree." As well as writing more than 50 books, Pip ran workshops and training courses all over the world, sharing his wisdom and "feelosophy". The influence of his groundbreaking work continues to inspire many people. Pip's family now work closely with Ian Long and Blobtree.
