It was Victor Buerger who labelled Alekhine as "wild", Capablanca as "dreary", and Lasker as "feeble". You can read more about this in Peter Hasenson's
British Bridge Almanack, 2004, page 110, which is the source. (It also says the four of them played bridge together at a pre-war Hastings tournament, but I don't see how that part is possible, unless I have misunderstood something.)
Victor Buerger was born in the Ukraine and naturalized in England in 1927. He ran a bridge club in London for some time.
For more about Buerger's chess activities, see Edward Winter's C.N. 6387:

It is interesting to see that, after Buerger's death in 1996, Christie's auctioned some chess score-books of his:
"The Property of the late Victor Berger (formerly Buerger):
BRITISH EMPIRE CLUB, MASTERS' CHESS TOURNAMENT, LONDON 1927 -- A set of ten score books, kept by ten of the twelve participants, Nimzowitsch, Tartakower, Vidmar, Bogoljubow, Reti, Colle, Buerger, Thomas, Yates and Fairhurst, each book containing 11 games with the moves recorded in pencil (some leaves in Nimzowitsch's book detached), original printed wrappers, modern cloth box. The other two participants, whose score books are no longer present, were Marshall and Winter."
