Miss Lenhart from comic 499: Scantron.

Miss Lenhart is the go-to character when Randall needs a teacher. She has white hair of shoulder length.

Miss Lenhart is usually named when she appears; however Randall uses her visual appearance from time to time, making it open for interpretation whether it's Miss Lenhart or not. The aimless student in 59: Graduation could for example be a young Miss Lenhart.

At 704: Principle of Explosion she is Mrs. Lenhart, but maybe this character is just the mom of Miss Lenhart.

The Lenhart family is mentioned in 416: Zealous Autoconfig, and in 1519: Venus, a teacher that looks just like her confirms that she is retiring in a month (in this comic she is not named though).
