Periodic Tabloid is an ongoing record of Tom Tritton’s actions and impressions as he makes the transition from college president to president and CEO of the Chemical Heritage Foundation, a library, museum, and center for scholars based in Philadelphia. Look for interactions with staff and stakeholders at CHF, reflections on science education, and comments on research in the sciences, all within the context of the history CHF exists to preserve. Expect to be challenged, informed, and amused as Tom shares his impressions from this new chapter of his life and career.
