Page "Alexander Grothendieck" Paragraph 16

While the issue of military funding was perhaps the most obvious explanation for Grothendieck's departure from IHÉS, those who knew him say that the causes of the rupture ran deeper.

Pierre Cartier, a visiteur de longue durée (" long-term guest ") at the IHÉS, wrote a piece about Grothendieck for a special volume published on the occasion of the IHÉS's fortieth anniversary.

The Grothendieck Festschrift was a three-volume collection of research papers to mark his sixtieth birthday ( falling in 1988 ), and published in 1990.
