Jonas Phillips Levy (1807–1883) was an American merchant and sea captain. Levy was granted the "freedom of the country" by the government of Peru for signal services rendered in the Peruvian Navy.
Jonas Phillips Levy was born in 1807 in Philadelphia in 1807 to Michael Levy and Rachel Phillips, a Jewish-American couple. His older brother Uriah Phillips Levy became the first Jewish commodore in the United States Navy.
His maternal grandfather Jonas Phillips immigrated from Germany in the mid-1700s. His great-great-grandfather had come from London and was one of a group of the earliest settlers in Savannah, Georgia. He was a descendant of Sephardic Jews who had fled to Europe and England after the Spanish Inquisition of the early 16th century.
Jonas Phillips Levy married Frances (Fanny) Mitchell on November 22, 1848. They had five children together:
Their son Jefferson Monroe Levy became a lawyer and financier in New York, and an admirer of Thomas Jefferson, as his father and uncle Uriah were. In 1879, at the age of 27, Jefferson Monroe financially took control of Thomas Jefferson's home Monticello, which his uncle Uriah Levy had purchased and restored in 1834. Like Uriah, the Jefferson Monroe invested his personal funds (in the amount of hundreds of thousands of dollars) to restore and preserve the mansion and 218 acres of grounds. He also purchased 500 acres that originally belonged to the plantation. In 1923 Monticello was purchased by the Thomas Jefferson Foundation to be preserved and operated as a house museum.
Jonas Levy became a merchant and sea captain. He commanded the U.S.S. America during the Mexican-American War (1846-1848), and was assigned to the transportation of troops to Veracruz. When the port surrendered, Levy was appointed its captain by Gen. Winfield Scott.
