Kim, J. (1998). The mind–body problem after fifty years. Royal Institute of Philosophy Supplement, 43, 3-21.
[Abstract]Fifty years of debate have shown, I believe, that the central core of the mind-body problem is constituted by two great and deep puzzles, consciousness and mental causation. And these two puzzles turn out to be intimately intertwined - the key to both is the question whether phenomenal properties of consciousness can be functionalized. I believe that is where we now stand with the mind-body problem, half a century after its reintroduction into philosophy by Ryle, Smart, Feigl and others.

Citing Place (1956) in context (citations start with an asterisk *):
* It is fair to say that the mind-body problem as we know it today had its proximate origins in a trio of papers published in the late 1950s: U. T. Place's 'Is Consciousness a Brain Process?', Fn 1 U. T. Place, 'Is Consciousness a Brain Process?', British Journal of Psychology 47/I (1956), 44-50. There were even earlier modern statements of the identity approach: e.g. Samuel Alexander, Space, Time, and Deity (London: Macmillan, 1920), vol. II, p. 9, where he says, 'The mental process and its neural process are one and the same existence, not two existences'; the psychologist Edwin G. Boring states, 'If we were to find a perfect correlation between sensation A and neural process a, a precise correlation which we had reason to believe never failed, we should then identify A and a ... it is scientifically more useful to consider that all psychological data are of the same kind and that consciousness is a physiological event' {The Physical Dimensions of Consciousness (New York: Dover reprint, 1963), p. 14). Boring's book was first published in 1933. in 1956, and J. J. C. Smart's 'Sensations and Brain Processes' and Herbert Feigl's 'The "Mental" and the "Physical"', published in 1958 and 1959 respectively. In these papers, Place, Smart and Feigl proposed an approach to the status of mind that has been variously called 'the mind-body identity theory', 'central-state materialism', 'type physicalism', and 'the brain-state theory'. In particular, it was the papers by Smart and Feigl that had a major philosophical impact, launching the debate that has continued to this day.
