1878–1947
Best remembered for writing practical books for bankers, this early 20th-century author helped explain commercial law and banking education in a clear, working-world way. His surviving books reflect a strong connection to the American Institute of Banking and the training of bank employees.

Richard William Hill (1878–1947) was an American writer whose known work centers on banking and business law. Public-domain and library records identify him as the author of Fifty Years of Banking Education: History of the American Institute of Banking, published in 1950, and as a co-author of Commercial Law.
The evidence available online links him closely with the American Institute of Banking. In the Project Gutenberg text of Commercial Law, Hill is described as a member of the New York Bar and secretary of the American Institute of Banking, which helps explain the practical, instructional character of his writing.
Although detailed biographical information about his personal life is scarce in the sources I could confirm, his work suggests a career devoted to professional education. Rather than writing for a purely academic audience, he appears to have focused on helping bankers understand the legal and institutional side of their field.
