Thaddeus Defrees was born in Boston, MA on September 27, 1855. His parents were Georgianna and William, a machinist.
Defrees's style of painting shows strong influence of the French Barbizon School. He was active in the White Mountains from at least 1877 until his death. He exhibited at the Boston Art Club in January, 1878. He was artist-in-residence at the Thorn Mountain House and, later (?), the Wilson Cottages.
