Bob Greenberg is a retired teacher who created a mission for himself: He interviews educators and makes short videos about their work. He also asks, in a separate video, which teachers made a difference in your life.

He calls his archive the Brainwave Video Anthology.

Here is a collection of more than 400 educators describing the teachers that mattered most to them.
