Who was Nixon's Secretary of State?

In July 1971, Nixon's National Security Adviser Henry Kissinger had secretly visited Beijing and laid the groundwork for Richard Nixon's visit to China. Almost as soon as the American President arrived in the Chinese capital he was summoned for a meeting with Chairman Mao who, unbeknown to the Americans, had almost died nine days earlier but was at that point feeling strong enough to meet Nixon. Secretary of State Bill Rogers was excluded from this meeting and the only other American present was National Security Council staffer (and later U.S. Ambassador to China) Winston Lord. To avoid embarrassing Rogers, Lord was cropped out of all the official photographs of the meeting.
