Thomas Prichard Rossiter (1818-1871) was born in New Haven, Connecticut. He first learned painting as an apprentice for a Mr. John Boyd, and also studied with Nathaniel Jocelyn. In 1838 he exhibited two paintings at the National Academy of Design, and in 1939 moved to New York City and opened a studio.

In 1840, Rossiter traveled to Europe with Asher B. Durand, John Kensett, and John Casilaer, and while there visited Rome with Thomas Cole. He decided to stay in Italy until 1846 when he moved to New York City and shared a studio with Kensett and Louis Lang. During this period he relied on portrait painting for his income, but also painted historical and religious paintings.

In 1851 Rossiter married Anna Ehrick Parmly and they toured Europe in 1853. They settled in Paris where Anna gave birth to twins Ehrick Kensett and Charlotte. Rossiter exhibited at the Exposition Universelle in Paris in 1855. Anna died shortly after the birth of their daughter Anna, and the family moved back to New York.

For a brief period of time Rossiter had an art gallery, exhibiting his work and the work of his friends. In 1860 he married Mary (Mollie) Sterling and moved his family to Cold Spring, New York on the Hudson River. He continued to paint portraits, historical, and religious paintings, and exhibited at the National Academy of Design and the Pennsylvania Academy of the Fine Arts, until his death in 1871.
