Two remarks. First 1950 is such a terrible cuttoff.  After C.I. Lewis published AKV, the currents all went against certainty based foundationalism -- think of Sellars, Wittgenstein, Carnap, Quine, Ryle -- all of whom dominated the early 50's and transformed epistemology so that by the mid sixties third person, fallibalist, causalist views had swept the Russell/Lewis sort of view almost entirely away.
Second,  The other thing whichg happened is that analytic philosophy became much narrower  avter the "linguistic turn", so that Pragmatism and continental strands of epistemoilogy which until that time had been in close conversation with analysis, dropped off the table. The idea that knowledge is experience rather than a proipositional attitude became very unpopular
