Emanuel Ethelbert Downham (March 23, 1839 – September 17, 1921), also known by his initials E.E., was an American businessman, miner, and mayor of Alexandria, Virginia, from 1887 to 1891, serving two terms.

[2] After moving to Alexandria in 1862, Downham decided not to directly join the war effort, and instead focused on the development of a liquor business.

He was very popular amongst the population and was elected outright in 1890, serving with distinction until 1891, before retiring from public office.

Downham married Sarah Miranda Price, daughter of a prominent merchant family, on November 16, 1865, and together they had 6 children, 5 of which lived into adulthood.

His son, Horace English Downham, along with his company, was involved with mining operations in Arizona, and Mexico in the late 1800s.
