Dr. James Kildare is a fictional character, the primary character in a series of American theatrical films in the late 1930s and early 1940s, an early 1950s radio series, a 1960s television series of the same name and a comic book based on the TV show, and a short-lived 1970s television series. The character was created by the author Frederick Schiller Faust, under the pen name Max Brand.

The character begins the film series as a medical intern; after becoming a doctor, he is mentored by an older physician, Dr. Leonard Gillespie. After the first ten films, the series eliminated the character of Kildare and focused instead on Gillespie. Lew Ayres, who had played the young doctor beginning in the second movie, was a conscientious objector and then a Medical Corpsman serving during World War II. He was replaced in the series by Van Johnson and Keye Luke, portraying young interns. Previously, Luke had become well known as Number One Son in the Fox Film Corporation Charlie Chan series, and he later became known for the role of Master Po in the TV series Kung Fu.

Kildare (Irish: Cill Dara, meaning "church of the oak") is a town in County Kildare, Ireland. Its population of 8,412 (2011 Census) makes it the eighth largest town in County Kildare and the 55th largest in the state, with a growth rate of 8.0pc since the 2006 census. Although Kildare gives its name to the county, Naas is the county town. The town lies on the R445, some 50 km west of Dublin – near enough for it to have become, despite being a regional centre in its own right, a commuter town for the capital.

Rich in heritage and history, Kildare Town dates from the 5th Century, when it was the site of the original ‘Church of the Oak' and monastery founded by St. Brigid. This became one of the three most important Christian foundations in Celtic Ireland.

It was said that Brigid's mother was a Christian and that Brigid was reared in her father's family, that is with the children of his lawful wife. From her mother, Brigid learned dairying and the care of the cattle, and these were her occupations after she made a vow to live a life of holy chastity. Both St. Mel of Ardagh and Bishop Mac Caille have been credited with the consecration of Brigid and some companions, after which the woman established a community beneath an oak tree, on a hill on the edge of the Curragh. Hence the name Cill Dara, the church of the oak.

Lionel Barrymore (April 28, 1878 – November 15, 1954) was an American actor of stage, screen and radio. He won an Academy Award for Best Actor for his performance in A Free Soul (1931), and remains perhaps best known for the role of the villainous Henry Potter character in Frank Capra's 1946 film It's a Wonderful Life. He was also a member of the illustrious theatrical Barrymore family.

Lionel Barrymore was born Lionel Herbert Blythe in Philadelphia, the son of actors Georgiana Drew Barrymore and Maurice Barrymore. He was the elder brother of Ethel and John Barrymore, the uncle of John Drew Barrymore and Diana Barrymore, and the great-uncle of Drew Barrymore. Barrymore was raised a Roman Catholic. He attended the Episcopal Academy in Philadelphia, Pennsylvania.

In her autobiography, Eleanor Farjeon recalled that when she and Barrymore were friends as toddlers, she would take off her shoes and he would kiss her feet.

He was married twice, to actresses Doris Rankin and Irene Fenwick, a one-time lover of his brother John. Doris's sister Gladys was married to Lionel's uncle Sidney Drew, which made Gladys both his aunt and sister-in-law.
