**Laurent-Moïse Schwartz** (5 March 1915 – 4 July 2002) was a French mathematician. He pioneered the theory of distributions, which gives a well-defined meaning to objects such as the Dirac delta function. He was awarded the Fields Medal in 1950 for his work on the theory of distributions. For several years he taught at the École polytechnique.

## Quotes[edit]

**To discover something in mathematics is to overcome an inhibition and a tradition. You cannot move forward if you are not subversive.***Un mathematicien aux prises avec le siecle*(1997)

- Trotskyism gave me … a remarkable education, clearly more advanced and sophisticated than that of most youngsters of my age. But by the extremism and sectarianism of its ideas, and by its stereotyped language, it neutralised me during the occupation. My judgment remains extremely severe on my own actions as well as those of the majority of the Trotskyist party during that period.
*A Mathematician Grappling With His Century*(2001)

**I have always thought that morality in politics was something essential, just like feelings and affinities.**- As quoted in his obituary in
*The Times*(July 2002)

- As quoted in his obituary in

- I was always deeply uncertain about my own intellectual capacity; I thought I was unintelligent. And it is true that I was, and still am, rather slow. I need time to seize things because I always need to understand them fully. Even when I was the first to answer the teacher's questions, I knew it was because they happened to be questions to which I already knew the answer. But if a new question arose,usually students who weren't as good as I was answered before me. Towards the end of the eleventh grade, I secretly thought of myself as stupid. I worried about this for a long time. Not only did I believe I was stupid, but I couldn't understand the contradiction between this stupidity and my good grades. I never talked about this to anyone, but I always felt convinced that my imposture would someday be revealed: the whole world and myself would finally see that what looked like intelligence was really just an illusion. If this ever happened, apparently no one noticed it, and I’m still just as slow. (...)At the end of the eleventh grade, I took the measure of the situation, and came to the conclusion that rapidity doesn't have a precise relation to intelligence.
**What is important is to deeply understand things and their relations to each other. This is where intelligence lies. The fact of being quick or slow isn't really relevant.**Naturally, it's helpful to be quick, like it is to have a good memory. But it's neither necessary nor sufficient for intellectual success.*A Mathematician Grappling With His Century*(2001). Quoted in slide no.22[1]

## Quotes about Schwartz[edit]

- Mathematics, politics and butterflies were the three great loves of Laurent Schwartz.
- Angelo Guerraggio, in "Laurent Schwartz: political commitment and mathematical rigor", in
*Mathematical Lives*(2011), p. 157-164

- Angelo Guerraggio, in "Laurent Schwartz: political commitment and mathematical rigor", in

- Schwartz never offered blind allegiance to Left or Right. Above all he was, in his own words, a man who hated to see systems not working properly.
