Albert Martin Kales (March 11, 1875 – July 26, 1922) was an American lawyer and legal scholar.
With the exception of one year as a visiting instructor at Harvard Law School, he performed most of his scholarly work at Northwestern University School of Law, at which he taught in 1902-1916 and 1917-1922.
He is best known for his 1914 work Unpopular Government in the United States, a work that helped pioneer the concept of appointing U.S.
judges rather than electing them in a partisan political process.
This concept spread in many states and is now commonly called the Missouri Plan, after the name of one of the first states to adopt it.
