# Who is this Mathematician from 17th century or earlier?. Possibly the 18th century, but before calculus had spread?

I'm looking for a mathematician from this time period, 17th century or earlier, its probably at a period where trigonometry was the most advanced math that existed. I'm not sure of the exact quote but it says something to the effect of "the field of mathematics has grown so large that it would take a man an entire lifetime to learn it all" (this is not an exact quote, but a paraphrase from what I remember of the quote). Any Idea who this mathematician was and/or the exact Quote?

Thanks

• Henri Poincaré is sometimes described as the last mathematician to have contributed to all of the various branches of the mathematics of his time, but we are well into the 19th century here. – Nick Apr 1 at 23:58
• Similar statements were made about Gauss, Poincare, Hilbert ... (Compare: quora.com/…, mathoverflow.net/questions/27881/…). How do you know this quote is even real (with the time parameters indicated in your question)? – Moishe Kohan Apr 2 at 15:51
