Boott was born on April 13, 1846 in Boston, Massachusetts. She was the daughter of the classical music composer Francis Boott and Elizabeth (née Lyman) Boott. Her mother, who died when she was 18 months old, was the eldest daughter of Boston Brahmin George Lyman and his first wife, who was the daughter of Harrison Gray Otis.

Boott was raised by her father in Italy. The pair returned to Boston in 1865.

Boott enrolled at the William Morris Hunt class for women in Boston in 1869, and also studied with Thomas Couture outside Paris for three consecutive summer (1876-1878). She (and her father) also spent the summer of 1879 studying with Frank Duveneck, an artist she and her father admired, in Munich.

Boott work was shown in multiple exhibitions throughout the United States in the early 1880s. Her first solo show was held in Boston at J. Eastman Chase's Gallery in 1882.

On March 25, 1886, in Paris, Boott married Duveneck. The two had been engaged off and on since 1881. Following their wedding, they lived at the Villa Castellani with her father. Their son, Frank Boott Duveneck, was born on December 18, 1886. He became an engineer and married Josephine Whitney, the daughter of Henry M. Whitney.

She lived later in Paris with her husband and son. She died there on March 22, 1888, of pneumonia. Her memorial in Allori Cemetery in Florence was created by her husband's friend from Cincinnati, Clement Barnhorn in 1891
