William Smith (8) (1769–1839)

William 'Strata' Smith (23 March 1769 – 28 August 1839) was an English geologist, credited with creating the first nationwide geological map. At the time his map was first published he was overlooked by the scientific community; his relatively humble education and family connections prevented him from mixing easily in learned society. Consequently, his work was plagiarised; financially ruined, he spent time in debtors' prison. It was only much later in his life that Smith received recognition for his accomplishments, and became known as the "Father of English Geology". [Wikipedia]
