Edward Lear was an English artist, illustrator, author and poet, and is known now mostly for his literary nonsense in poetry and prose and especially his limericks, a form he popularised. His epilepsy, which he developed as a child, may have been inherited (his elder sister Jane had frequent seizures and died young). Lear was ashamed of his epilepsy and kept it a secret. He did, however, record each seizure in his diary.
