This retrospective celebrates The Clearing House centennial year of publishing and a reminiscence of what authors and readers valued in their teaching practice. The work here considers a 1974 article by Timothy Bergen Jr., "The Young Teacher in the Age of Aquarius," with a look over time at shifting attitudes of and about teaching and teachers. Educators inhabit a workplace today different from the youthful optimism of the 70s. Two themes, mobility and activism, from Bergen's piece demonstrate how far educators have come in fifty years, but in other ways, how they have remained tethered to lasting policy issues.
