Born March 7, 1902, in Beijing, Ingram was the daughter of American Congregational missionary James Henry Ingram and Myrtle Belle Ingram, his second wife. Her passport and a New York Times article give her sisters as Miriam Ingram and Ruth Ingram. Other siblings were Kathryn Ingram, Robert Ingram, and Lewis Ingram.
Ingram was the tutor to Wanrong, the last empress of China. She lived in the Forbidden City, where she taught Wanrong, who was married to Puyi in December 1922. Ingram graduated from Wellesley College, Wellesley, Massachusetts, in 1922, the same year she returned to China, and began teaching Wanrong.
Accounts of Isabel Ingram in Richard Halliburton, ''The New York Times'' and ''Time''
Famous in his era, travel-adventure writer Richard Halliburton wrote his parents in December 1922, saying that he called on "the young American tutoress of the Empress of China." He added that he found the visit quite interesting. The young Ingram was petite and quite attractive. He wrote that on Christmas Eve he "went for a walk about the city wall with Miss Ingram," and also said that "the Royal Pair were only married a day or two before," adding that "this girl" and Reginald Johnston, Pu Yi's tutor, were the only people of European stock "at the great ceremony." In his book The Royal Road to Romance, he wrote that the empress was not to be outdone by the emperor with his tutor, and that Ingram taught her the speech, modes, and manners of the West. As well, the two girls tried to look like one another and traded clothes. A 21 November 1934New York Times article states that the empress received part of her education from two American women. It names the women as Miriam Ingram and Isabel Ingram, and says they are daughters of a Congregational missionary from Philadelphia. The article further explains that from them the empress learned English, history and something about life in the Western world. On 12 May 1924, Time magazine had a piece titled "Henry The Democrat," "Henry" referring to a name adopted by Puyi, who, according to Time had a "beautiful consort" with the court name, Elizabeth. The article states, "Elizabeth was accompanied by Miss Isabel Ingram, graduate of Wellesley, her American tutor."
Scholarly writing
As a reflection of her interest in Chinese art and culture, for The Pennsylvania Museum Bulletin she wrote "A Scroll of the Eight Views by Chang Lung Chang" as well as "The Siren Collection of Chinese Sculpture," both between 1927 and 1929.
