Paul Richard Halmos bol americký matematik.
Je známy najmä vďaka významnému prínosu v oblastiach teórie pravdepodobnosti, štatistiky, funkcionálnej analýzy , ergodickej teórie, teórie miery a matematickej logiky. Je známy aj ako autor veľkého množstva matematických kníh a vďaka tzv. Halmosovmu symbolu - typografickej značky
◻
{\displaystyle \square }
alebo ∎, ktorá sa používa v niektorých matematických textoch na označenie konca dôkazu.

Kontext: What does it take to be [a mathematician]? I think I know the answer: you have to be born right, you must continually strive to become perfect, you must love mathematics more than anything else, you must work at it hard and without stop, and you must never give up.

Kontext: Mathematics is not a deductive science — that's a cliché. When you try to prove a theorem, you don't just list the hypotheses, and then start to reason. What you do is trial and error, experimentation, guesswork. You want to find out what the facts are, and what you do is in that respect similar to what a laboratory technician does. Possibly philosophers would look on us mathematicians the same way as we look on the technicians, if they dared.
