on August 25, 1819, the son of Isobel McQueen and William Pinkerton. He left school at the age of 10 after his father's death. Pinkerton read voraciously and was largely self-educated. A cooper by trade, he was active in the Scottish Chartist movement as a young man. He was not raised in a religious upbringing, and was a lifelong atheist. Pinkerton emigrated to the United States in 1842. In 1843, he heard of Dundee Township, Illinois, fifty miles northwest of Chicago on the Fox River. He built a cabin and started a cooperage, sending for his wife in Chicago when their cabin was complete. As early as 1844, Pinkerton worked for the Chicago abolitionist leaders, and his Dundee home was a stop on the

Detective

Pinkerton first became interested in criminal detective work while wandering through the wooded groves around Dundee, looking for trees to make barrel staves, when he came across a band of counterfeiters, who may have been affiliated with the notorious Banditti of the Prairie. After observing their movements for some time he informed the local sheriff, who arrested them. This later led to Pinkerton being appointed, in 1849, as the first police detective in

. His agents often worked undercover as Confederate soldiers and sympathizers to gather military intelligence. Pinkerton himself served on several undercover missions as a Confederate soldier using the alias Major E.J. Allen. He worked across the Deep South in the summer of 1861, focusing on fortifications and Confederate plans. He was found out in Memphis and barely escaped with his life. This counterintelligence work done by Pinkerton and his agents is comparable to the work done by today's U.S. Army Counterintelligence Special Agents in which Pinkerton's agency is considered an early predecessor. He was succeeded as Intelligence Service chief by Lafayette Baker; the Intelligence Service was the predecessor of the U.S. Secret Service. His work led to the establishment of the Federal secret service. Military historians have been strongly critical of the intelligence Pinkerton provided for the Union Army, which for the most part was undigested raw data. In the view of T. Harry Williams, Pinkerton's work was "the poorest intelligence service any general ever had." Pinkerton's estimates of Rebel troop numbers, derived from his credulous interrogations of Confederate prisoners, deserters, refugees, escaped slaves ("contrabands"), and civilians unused to counting large bodies of men, badly exaggerated the size of those formations, sometimes almost doubling their actual strength. Pinkerton's numbers caused McClellan to consistently believe that he was drastically outnumbered by the Confederate forces he faced. McClellan's action in the face of what he believed were overwhelming odds were unduly cautious, causing him to avoid offensive actions almost completely in favor of

. He was hired by the railroad express companies to track outlaw Jesse James, but after Pinkerton failed to capture him, the railroad withdrew their financial support and Pinkerton continued to track James at his own expense. After James allegedly captured and killed one of Pinkerton's undercover agents (who was working undercover at the farm neighboring the James family's farmstead), he abandoned the chase. Some consider this failure Pinkerton's biggest defeat. In 1872, the Spanish Government hired Pinkerton to help suppress a

If Pinkerton knew this, then it directly contradicts statements in his 1883 book ''The Spy of the Rebellion'', where he professes to be an ardent abolitionist and hater of slavery. The Spanish government abolished slavery in 1880 and a Royal Decree abolished the last vestiges of it in 1886.

Writings

Pinkerton produced numerous popular detective books, ostensibly based on his own exploits and those of his agents. Some were published after his death, and they are considered to have been more motivated by a desire to promote his detective agency than a literary endeavour.
