You might like this story about Freeman Dyson and Richard Feynman having a road trip:

https://youtu.be/1Rr3ZWt1ULQ (the whole interview is very interesting and contains a lot of stories of meeting other physicists and mathematicians, it’s broken up into a series of snippets of a few minutes each on youtube)

In the end this trip lead to one of Dyson’s biggest contributions to physics, he could talk to Feynman about his research on the road trip and visited Schwinger afterwards and as such was in a unique position to recognise and formalise the equivalence of Feynman’s, Schwinger’s and Tomanaga's formulations of quantum electrodynamics. This was an important step towards the acceptance of Feynman diagrams.

I also really liked "Maker of Patterns”, Dyson’s autobiography through letters.
