Samuel Krempp is a PhD student in mathematics, at the CMLA in the 'Ecole Normale Supérieure' de Cachan (France). He spends most of his time implementing complicated image recognition algorithms, and thus had to get acquainted with C++.
He enjoys many other things - one of them is diving in wonderful, warm, sunny seas when he can afford it. And obviously, another is eating camembert and bread, drinking wine... and other activities typical of a French guy :)
He's the author of the Boost Format library.
