"hedgehog". From an ancient Greek fragment attributed to Archilochus: πόλλ' οἶδ' ἀλώπηξ, ἀλλ' ἐχῖνος ἓν μέγα ("a fox knows many things, but a hedgehog one important thing"). See The Hedgehog and the Fox.
I do not know of any specific word for this kind of person, "generalist" would come to mind as someone who takes a general view of things.
