Dwight Whitney Marsh (1823–1896)[1] was an American artist, missionary and historian. He is known for his 1869 book titled The Tennessean in Persia and Koordistan'.[2] This book, published in 1869, details the experiences of Samuel Audley Rhea, a missionary in Persia and Kurdistan. It provides insights into missionary activities and life in those regions during the 19th century. The book is also a source for studying the 19th century geography and culture of Kurdistan and Persia. Marsh wrote many letters to his families many of which are preserved in university archives across North America.[3]
