It was with great sadness that I read that two of my gifted biology professors had recently died. Of note, in addition to their teaching and research accomplishments, is the coincidental timing of their passing. 

Linked with a third legendary Princeton professor, we have now said goodbye, in one month, to three amazing giants of the biology world: on Feb. 7, at age 98, John Bonner [7] (known affectionately as “Slime Mold” to generations of Princeton premeds); on Feb. 24, at age 97, Arthur Pardee [6]; and on March 3, at age 99, Bill Jacobs [6] (In Memoriam, March 20 and April 10). Did they also find a fountain of youth while at Princeton?
