A few. Carl Sagan and Rory Stewart are two that work a bit like Psalms for me (apologies to religious folks; I don’t mean to offend. I mean in the sense that I often find a new perspective by going back to one of their books). For tech specifically, Fred Brooks. His work is a good source of guidance whenever things go south at work for the same reasons they always have; or at least since 1975, when The Mythical Man-Month was written.
