Initial Reactions

by C. Kenneth Stern and Mike Selinker
Answer: RUDGE

Each clue can be answered by two persons whose names fit the pattern of "?. Middlename Lastname". A "fusion" reaction means that you add the alphanumeric position of the two first initials to get a new letter (e.g., A+B=C), while a "fission" reaction means you subtract the earlier one from the later one (e.g., C-B=A). Reading the new letters in order spells MIT CHAIR ENDOWER E THIS ALLEN. An MIT Media Center professorship currently held by John Maeda was endowed by E. RUDGE Allen.
