He served as a delegate for Maryland in the Continental Congress in 1776 and 1777.^[1] He served for over twenty-five years, beginning in 1778 until his retirement in 1806 as the first chief judge of the Maryland Court of Appeals. His record of longevity still stands today.^{[citation needed]}

Benjamin Rumsey was born on October 6, 1734, to Sabina (née Blaidenburgh) and William Ramsey^[2] at Bohemia Manor in Cecil County Province of Maryland. After attending Princeton, he read law and was admitted to the bar. He settled in Joppa about 1768 and lived there the rest of his life.

Rumsey was first elected to Maryland's lower house in 1771 as a member for Cecil County.^[2] After Harford County was formed in 1773, he represented it.^{[citation needed]} He also represented the county in the Maryland conventions held between 1775 and 1776. Maryland sent him as a delegate to the Continental Congress in 1776 and 1777.^[2] He was elected as colonel of the lower battalion of the Harford County Militia on January 6, 1776.^[2]

When a new state superior court (the Maryland Court of Appeals) was created in 1778, Benjamin Rumsey was appointed as its first chief justice. He held that post until his retirement in 1806.^[2]

Rumsey married Mary Hall on March 24, 1768. He had three children: Benjamin Jr., John and Hannah.^[2] His cousin was James Rumsey, engineer known for his early steamboat experiments.^[3]
