HG Wells
A journalist, sociologist, historian and author, HG Wells wrote more than a hundred books including 'The Invisible Man', 'The War of the Worlds' and 'The Time Machine'.
His futuristic, prophetic visions grappled with the profound choices faced by mankind in respect of science, technology, war and social order on a global scale.
Wells's diagnosis of diabetes (distinctions of Type 1 and Type 2 did not exist then) came in his early 60s, around 1930, and led to him giving up his teaching career.
In July 1931 he became a private patient of the famous physician RD Lawrence, and in 1934 he announced the formation of the Diabetic Association via a letter to the Times newspaper.
