Edward Lawrence Doyle (1886-1954), Lafayette resident from 1908 to 1912 and UMWA Dist. 15 secretary-treasurer based in Denver from 1912 to 1917, is better known for his involvement in the fateful 1914 Ludlow Massacre, where he played a key role in communicating to national media the union's perspective of the killings. As part of that job, he corresponded regularly with labor activist Mother Jones and with author Upton Sinclair, who wrote “King Coal,” an exposé on the dangerous conditions Colorado coal miners faced. Doyle was entrusted by Sinclair to proofread “King Coal” for accuracy prior to its release in 1917.
