Ty for the show recommendation!

I am pretty familiar with much of the (mathematics) story for Newton and Euler; while they did accelerate things, famously much of calculus from Newton would have emerged from others within a decade or two. And it's not uncommon to be working anywhere in mathematics and stumble upon a 'new to me' result which is, inevitably, really due to Euler. This isn't to say they did bad work, just that the large part of their work was available by paths with few 'breakthroughs'.
