Roy Prentice Basler (November 19, 1906 – October 25, 1989)[1] was an American historian who rose to prominence in the middle of the 20th century.
Basler was most famous for editing the collected works of Abraham Lincoln.
[2] Basler was born in St. Louis and attended Central Methodist College in Fayette, Missouri, before receiving his PhD in American literature at Duke University.
[3][4] Basler's definitive eight volume collection of Lincoln's writings was published in 1953 and a supplement was released in 1974.
It has been described as "the principal source"[5] and "the most invaluable work of all" for Lincoln studies.
