Bev Aisbett is the author/illustrator of 16 books, two of which were a reworking of Allen Carr's Easyway titles into Bev's distinctive cartoon format. Bev is best known for her highly successful self-help books, most notably Living with IT and Taming the Black Dog, produced in the same accessible illustrated format as the Easyway books. Bev's 8 self-help titles are seen as standard texts on the subject of anxiety and depression by counsellors, psychologists, health workers and sufferers alike in Australia and overseas. Allen Carr was born in 1934. The first in his family to enter the 'professions', he received articles from a prestigious firm of City accountants and began a career in a business he soon came to loathe. After filling a series of highly paid positions, punctuated by a two-year stint in the army as part of his country's National Service programme, Allen reached the nadir of his disillusionment with accountancy. Fed up with the old boys' network and complacent attitude, he took a completely different direction, starting a property development business, initially with a friend and later striking out on his own with his wife, Joyce. By this point in his life, Allen was chain-smoking 100 cigarettes a day, despite the fact that his older sister, Marion, and his father had died prematurely of lung cancer.

After repeated failed attempts to stop smoking, Allen's conversion into a non-smoker was as dramatic as it was totally unexpected. His discovery of the kernel of what would become the Easyway method brought about another life-changing decision: to dedicate his life to the fight against nicotine addiction. Allen made this decision in July 1983. Since then he has built Easyway into an international brand with clinics in over 20 countries across the world, and developed his method into the most effective stop smoking therapy currently available. In 2006 Allen was diagnosed with lung cancer and passed away that November.
