Turing was interested in a bunch of other stuff, but what people know about is the Computer and his war work (at Bletchley Park). His work on say Morphogenesis (why are zebra stripes different on each animal?) is little known.

But Turing probably isn't more important to how you get from the Treaty of Bern in 1874 (creating the UPU thus you could now practically write letters in Paris and send them to New York and it Just Works™ albeit it's expensive and slow) to the Internet than, say, Godel (more fundamental observations about the nature of mathematics that underpin computation) or Grace Hopper (the first compiler although today we'd say this is only a linker). Her Navy bosses couldn't immediately see any value for it. But Grace is apparently the first to make use of the meta-applicability of computing - the minutiae of actually programming the computer are tiresome, a lot of rote tasks perfectly suited to a machine, so, why not have the computer do those parts for you?
