I found something out the other day; McTaggart; the author of The Unreality of Time, was a philosopher of the infamous British Idealist phase in the history of philosophy.
I find this striking for two reasons:
i. McTaggart’s thesis was very influential to the development of future work in the philosophy of time.
ii. McTaggart is interesting in relation to the founders of British analytic philosophy in two respects; (a); he taught Russell and Moore and influenced the former into Hegelian tendencies; (b) this period of influence was short as Russell was known very seminally for opposing Idealist tendencies.
