Surely he was. (Remember his theory of levers, and his calculations of centres of gravity.) But he was also an outstanding pure mathematician. For example, Riemann sums just express in modern notation the way that Archimedes handled integrals. If you read Archimedes, you won't always find it easy, but you will realize that you are in the presence of an impeccable mathematician.

I don't know who "they" are. Textbook authors often make simplistic remarks like that in historical footnotes, which are uncritically copied from one book to another. In fact most areas of thought seem to have built up gradually through the work of many people.
