Guest conductors in the 1970s included Erich Leinsdorf, Carlo Maria Giulini, Eugen Jochum, Riccardo Chailly, Klaus Tennstedt and Solti. When Haitink announced in 1977 that he would step down as principal conductor at the end of the 1978–79 season, Solti, who had been principal guest conductor since 1971, agreed to succeed him.
