question / pregunta:
"Peace if possible, justice at any rate"
This quotation is written above the stage in the auditorium at DuSable High School where I work on the South Side of Chicago. There is some discussion about the origin of the quote but nobody seems to be sure. It might be from Wendell Phillips? I am a librarian but have not been able to find out what its origin is. The school was built in 1935 and opened in 1936 to replace the Wendell Phillips High School which burned down.

We don't seem to have gotten anywhere tracking down the Brown and/or Luther origins, but since the original query was related to Wendell Phillips (which we did confirm), and it's been a couple of months, I am switching this to "answered." Anyone coming upon this question in the future who may have some expertise in the work of John Brown or Martin Luther - we await your input!
