The son of Reverend and Mrs. John D. Ellis, Sidney Emerson Ellis joined the Royal Naval Air Service in August 1916. Posted to 4 Naval Squadron, he scored his first two victories in the spring of 1917 flying the Sopwith Pup. In July 1917, Ellis scored three more victories flying the Sopwith Camel. He was one of the first two pilots to score a victory with this aircraft, shooting down a Gotha bomber northwest of Ostende on the morning of 4 July 1917. Five days later, he was killed when his Camel went into a spin and crashed.
