IN: Abner Doubleday (June 26, 1819 - January 26, 1893) was a career United States Army officer and Union general in the American Civil War. He fired the first shot in defense of Fort Sumter, the opening battle of the war, and had a pivotal role in the early fighting at the Battle of Gettysburg. Gettysburg was his finest hour, but his relief by Maj. Gen. George G. Meade caused lasting enmity between the two men.

At the start of the Battle of Gettysburg, July 1, 1863, Doubleday's division was the second infantry division on the field to reinforce the cavalry division of Brigadier General John Buford. When his corps commander, Major General John F. Reynolds, was killed very early in the fighting, Doubleday found himself in command of the corps at 10:50 am. His men fought well in the morning, putting up a stout resistance, but as overwhelming Confederate forces massed against them, their line eventually broke and they retreated back through the town of Gettysburg to the relative safety of Cemetery Hill south of town. It was Doubleday's finest performance during the war, five hours leading 9,500 men against ten Confederate brigades that numbered more than 16,000. Seven of those brigades sustained casualties that ranged from 35 to 50 percent, indicating the ferocity of the Union defense. On Cemetery Hill, however, the I Corps could muster only a third of its men as effective for duty, and the corps was essentially destroyed as a combat force for the rest of the battle; it would be decommissioned in March 1864, its surviving units consolidated into other corps. On July 2, 1863, Army of the Potomac commander Maj. Gen. George G. Meade replaced Doubleday with Major General John Newton, a more junior officer from another corps. The ostensible reason was a false report by XI Corps commander Major General Oliver O. Howard that Doubleday's corps broke first, causing the entire Union line to collapse, but Meade also had a long history of disdain for Doubleday's combat effectiveness, dating back to South Mountain. Doubleday was humiliated by this snub and held a lasting grudge against Meade, but he returned to division command and fought well for the remainder of the battle. He was wounded in the neck on the second day of Gettysburg and received a brevet promotion to colonel in the regular army for his service. He formally requested reinstatement as I Corps commander, but Meade refused, and Doubleday left Gettysburg on July 7 for Washington. Doubleday's indecision as a commander in the war resulted in his uncomplimentary nickname "Forty-Eight Hours."

IN: O'Neill was born in a hotel, the Barrett House, at Broadway and 43rd Street, on what was then Longacre Square (now Times Square). A commemorative plaque was first dedicated there in 1957. The site is now occupied by 1500 Broadway, which houses offices, retail, and ABC Studios. He was the son of Irish immigrant actor James O'Neill and Mary Ellen Quinlan, who was also of Irish descent.

O'Neill was married to Kathleen Jenkins from October 2, 1909 to 1912, during which time they had one son, Eugene O'Neill, Jr. (1910-1950). In 1917, O'Neill met Agnes Boulton, a successful writer of commercial fiction, and they married on April 12, 1918. They lived in a home owned by her parents in Point Pleasant, New Jersey, after their marriage. The years of their marriage--during which the couple lived in Connecticut and Bermuda and had two children, Shane and Oona--are described vividly in her 1958 memoir Part of a Long Story. They divorced in 1929, after O'Neill abandoned Boulton and the children for the actress Carlotta Monterey (born San Francisco, California, December 28, 1888; died Westwood, New Jersey, November 18, 1970). O'Neill and Carlotta married less than a month after he officially divorced his previous wife. In 1929, O'Neill and Monterey moved to the Loire Valley in central France, where they lived in the Chateau du Plessis in Saint-Antoine-du-Rocher, Indre-et-Loire. During the early 1930s they returned to the United States and lived in Sea Island, Georgia, at a house called Casa Genotta. He moved to Danville, California in 1937 and lived there until 1944. His house there, Tao House, is today the Eugene O'Neill National Historic Site. In their first years together, Monterey organized O'Neill's life, enabling him to devote himself to writing. She later became addicted to potassium bromide, and the marriage deteriorated, resulting in a number of separations, although they never divorced. In 1943, O'Neill disowned his daughter Oona for marrying the English actor, director, and producer Charlie Chaplin when she was 18 and Chaplin was 54. He never saw Oona again. He also had distant relationships with his sons. Eugene O'Neill, Jr., a Yale classicist, suffered from alcoholism and committed suicide in 1950 at the age of 40. Shane O'Neill became a heroin addict and moved into the family home in Bermuda, Spithead, with his new wife, where he supported himself by selling off the furnishings. He was disowned by his father before also committing suicide (by jumping out of a window) a number of years later. Oona ultimately inherited Spithead and the connected estate (subsequently known as the Chaplin Estate). In 1950 O'Neill joined The Lambs, the famed theater club.
