Readers of a certain age may remember Tom Lehrer’s song “,” in which the then-Harvard math professor and musical satirist patter-sang, a la Gilbert and Sullivan, the name of every element in the periodic table.

When I was a musical theater nerd in high school, I co-directed a musical revue in my senior year. The other directors and I thought we had the whole thing precast, but during auditions, a hitherto unremarkable singer bowled us over with her rendition of this serious tongue twister. (You can how impressive this was.) We borrowed a lab coat and a wall-sized copy of the periodic table from the school’s science department to hang behind her. At every performance, that song brought the house down. The big chart disappeared after closing night, and one of my fellow directors either had to pay for it or forfeit her diploma.

That was the last time I thought about the periodic table until an ASBMB Today planning meeting late last year when Quira Zeidan, the society’s education and public outreach coordinator, told us that 2019 was the 150th anniversary of the year Dmitri Mendeleev first published his tabular display of the elements.

She wasn’t just sharing science trivia. In her heart of hearts, Quira is a teacher, and she offered to write a series of articles for ASBMB Today highlighting elements of significance in the biochemical realm.

There’s nothing an editor likes better than the promise of a timely series (and guaranteed content), so I was delighted, but Quira gave us something more than that. As regular ASBMB Today readers know, she has provided a wonderfully coherent series of lessons that clearly explain everything from where the elements originate to their roles in human health. Every month, I’ve looked forward to learning something new from this series. And in this issue, with nickel and zinc, I’m sad to see it end.

This month may mark the end of the (bio)chemical elements in ASBMB Today, but plans are afoot to build educational programs around these 11 articles — complete with experiments. If this resource would be useful to you or any of your colleagues, contact Quira.

Thanks to all our readers for celebrating the International Year of the Periodic Table with us — and thank you, Quira, for being as cool a teacher as Tom Lehrer.
