**The four princes in summit 200, ten years ago. **

In 2014, Péter Frankl, Zoltán Füredi, Ervin Győri and János Pach are turning 60 and **summit 240** is a conference this week in Budapest to celebrate the birthday of those ever-young combinatorics princes. I know the four guys for about 120 years. I first met Peter and Janos (together I think) in Paris in 1979, then Zoli at MIT in 1985 and I met Ervin in the mid late 90s in Budapest. Noga Alon have recently made the observation that younger and younger guys are turning 60 these days and there could not be a more appropriate time to realize the deep truth of this observation than this week.

The mathematical work of our eminent birthday boys was and will be amply represented on this blog. So let me give just one mathematical link to János’s videotaped plenary lecture at Erdős Centennial conference. (Click on the picture to view it. Here is again the link just in case.)

And now, here are a few pictures of our birthday boys.

Joseph MalkevitchDear Gil,

Paradoxically, some older and older folk are getting younger and younger as well – you know who you are!

Cheers,

Joe

Gil KalaiPost authorThanks Joe, the summer I turned thirty I rented an appartment in NYC with Peter Frankl and Voita Rodl and I remember that Peter (who is just a year older than me) gave me a birthday card where he wrote something visionary yet hard to believe like : “one can enjoy life even at fourty!!”
