The Door Into Summer

[Amazon Link]

Continuing on the reread-Heinlein project. This one is a favorite. Short, and simple. Or, as simple as a time-travel tale can be.

First published in 1956, it opens in the far future of … 1970. The hero and narrator, Daniel Boone Davis, is a genius engineer/inventor, working in partnership with his trusted pal Miles, in love with their robotics company's secretary, Belle.

This turns out to be a mistake, as Miles and Belle successfully conspire to wrest control of the firm from him. And when he credibly threatens to raise a stink, they dispose of him neatly, by putting him in "cold sleep", until the unimaginably distant future of … the year 2000.

Awakening in 2000, Dan is flummoxed by the incredible advances. But when he tries to get back into his engineering profession, he can't help but notice that some bright boy has long since stolen the ideas that only existed in his head. What's going on?

Nobody's made this into a movie, unfortunately, but you'll notice its sci-fi DNA percolating into a lot of other time-travel yarns, like Back to the Future and Futurama.
