Robert Stroud, American ornithologist and author (b. 1890)

Robert Franklin Stroud (January 28, 1890 – November 21, 1963), known as the "Birdman of Alcatraz", was a convicted murderer, American federal prisoner and author who has been cited as one of the most notorious criminals in the United States. During his time at Leavenworth Penitentiary, he reared and sold birds and became a respected ornithologist. From 1942 to 1959, he was incarcerated at Alcatraz, where regulations did not allow him to keep birds. Stroud was never released from the federal prison system; he was imprisoned from 1909 to his death in 1963.

Born in Seattle, Washington, Stroud ran away from his abusive father at the age of 13. By the time he was 18, he had become a pimp in the Alaska Territory. In January 1909, he shot and killed a bartender who attacked his mistress, a crime for which he was sentenced to 12 years in the federal penitentiary on McNeil Island in Puget Sound. Stroud gained a reputation as a dangerous inmate who frequently had confrontations with fellow inmates and staff. In 1916, he stabbed and killed a guard. Stroud was convicted of first-degree murder and sentenced to death by hanging, but after several trials, his sentence was commuted to life imprisonment in solitary confinement.

In 1920, while in solitary confinement at the federal penitentiary of Leavenworth, Stroud discovered a nest with three injured sparrows in the prison yard. He cared for them and within a few years had acquired a collection of about 300 canaries. He began extensive research into birds after being granted equipment by a prison-reforming warden. Stroud wrote Diseases of Canaries, which was smuggled out of Leavenworth and published in 1933, as well as a later edition (1943). He made important contributions to avian pathology, most notably a cure for the hemorrhagic septicemia family of diseases, gaining much respect and some level of sympathy among ornithologists and farmers. Stroud ran a successful business from inside prison, but his activities infuriated the prison staff. He was transferred to Alcatraz in 1942 after it was discovered that Stroud had been secretly making alcohol by using some of the equipment in his cell.

Stroud began serving a 17-year term at Alcatraz Federal Penitentiary on December 19, 1942, and became inmate #594. In 1943, he was assessed by psychiatrist Romney M. Ritchey, who diagnosed him as a psychopath, with an I.Q. of 112. Stripped of his birds and equipment, he wrote a history of the penal system.

For all the negative reports written about Robert Stroud and his behavior, in what came to be called The Battle of Alcatraz in May 1946, he made efforts to protect other inmates. Then fifty-six years old, Stroud climbed over the third tier railing and lowered himself to the second tier, then dropped onto the floor of D Block. In what seemed to be a valiant move, he started closing the front solid steel doors of the six isolation cells to protect the helpless men. Stroud yelled to the Warden, explaining that there were no firearms in D Block and that those involved in violence had retreated to another section of the prison. He made it clear that many innocent men would die if the guards continued to fire into D Block.

In 1959, Stroud was transferred to the Medical Center for Federal Prisoners in Springfield, Missouri, where he remained until his death on November 21, 1963.
