Griffith Thomas (1820–1879) was an American architect.
[1] Architecture writer Christopher Gray called him "one of the most prolific architects of the period", referring to the mid-19th century.
"[3] Many of his notable buildings are found in New York City.
Griffith Thomas was interred at Green-Wood Cemetery, in Brooklyn, New York in 1879.
His own marble monument is simple in comparison to the ornate structures he built during his lifetime.
