Biography[]
William S. Wallace was born in Philadelphia, Pennsylvania, and he trained as a doctor before moving to Springfield, Illinois in 1836 and marrying Abraham Lincoln's future sister-in-law in 1839. He came to be Lincoln's family physician, and unsuccessfully sought a federal appointment on the basis of his Whig loyalties. After Lincoln became President in 1860, he appointed Wallace a US Army paymaster, and he contracted a urinary disease in Mississippi and died in 1867.
