Apple
This is not the tree Newton sat under. It is a living descendant of that one, the apple at Woolsthorpe Manor in Lincolnshire, and it stands in the President's Garden off MIT's Infinite Corridor, where it bears fruit like any other apple tree.
MIT's own facts page records it as a gift from Ed Vetter, class of 1942, and gives no planting date. Nobody appears to have written one down. If you know when it went in, tell us.
What is documented is the morning somebody came to take a piece of it. In 2009 the Tufts cosmologist Alexander Vilenkin asked the MIT physicist Alan Guth about the tree, MIT's president Susan Hockfield gave her permission, and a Tufts grounds manager drove over and cut three branches off it. Those are now a tree in Medford. An apple cultivar only travels by hand, one graft at a time.
The cultivar is worth a sentence. Descendants of the Woolsthorpe tree are 'Flower of Kent' wherever they turn up, a big, coarse cooking apple nobody grows for flavour any more, which is why it is named that way here; MIT's own page does not say so.
MIT's Main Group buildings were reported open to the public on weekdays, 6am to 7pm, in December 2022. That was a few years ago and campus rules move, so treat the hours as a good bet rather than a promise.
