Samuel Brady was born in Delaware. He moved to Baltimore, Maryland at an early age and entered the retail dry goods business. He owned a business on North Gay Street in Baltimore.^[1][2]

In 1834, Brady ran for the Maryland House of Delegates, but lost. In 1836, Brady was appointed City Collector by Mayor Samuel Smith. Brady served as a member of the First Branch of the Baltimore City Council for two one-year terms. In his second term, he served as president of the division.^[1][2] Brady ran as a Democrat for Mayor of Baltimore in 1840, defeating incumbent Sheppard C. Leakin.^[3] Brady became mayor on November 2, 1840. He served until March 9, 1842, resigning due to a disagreement with the City Council on the city's purchase of a large amount of Baltimore and Ohio Railroad stocks.
