The constant fighting between Schmidhuber and LeCunn should be well known in here. But in my opinion, both of them have been involved with fantastic papers that are both painless to read and full of useful info:

CTC loss: https://www.cs.toronto.edu/~graves/icml_2006.pdf

DeepLearning: https://hal.science/hal-04206682/document

And both of these papers are new and on more recent research, so it's not just old papers that are good. It's just that there is a flood of bad new papers drowning out a constant signal with additional noise.
