In my haste to post the 250th artifact, the MIT economics faculty group picture of 1976, I incorrectly identified the Associate Dean of the Sloan School. For subscribers that means you either need to note that “Abraham Siegel” and not “Jeremy Siegel” is the correct identification or go back to the posting.
Surely this is a teachable moment: it is worth checking back if you are interested in some particular post. As a rule my post-posting corrections are done without fanfare.
