Of all BBC conductors, which did the leader like best?

From a lovely Times obit today of Bela Dekany, concertmaster of the BBC Symphony:
… He joined the BBC Symphony Orchestra in 1968 and spent more than 22 years sharing the leader’s chair with Eli Goren and Rodney Friend. Over the years he worked with many fine conductors, including Colin Davis, Pierre Boulez, Gennadi Rozhdestvensky, John Pritchard and Andrew Davis. He was closest to Günter Wand, the orchestra’s demanding principal guest conductor, and the pair forged a powerful bond, with Dekany deploying his finest negotiating skills when arbitrating between the players and this irritable maestro.

Who would have expected a Belsen survivor to bond with an austere Rhineland Catholic.
