John Spencer Palmer (September 10, 1935 – August 3, 2013) was a long time news correspondent for NBC News, American television broadcaster and news anchor.
NBC:
Palmer worked for the NBC network over the course of 40 years, first from 1962 to 1990; and again from 1994 until his retirement in 2002. During his tenure with NBC News, he held several positions, including correspondent stints in Chicago, Paris, and the Middle East; White House correspondent (1979–1982); news anchor for The Today Show (1982–1989); and anchor for NBC News at Sunrise (1989–1990).
In April 1980, Palmer reported on the failure of Operation Eagle Claw, the mission to rescue the American hostages held by Iran. This earned him the Merriman Smith Memorial Award for excellence in presidential news coverage, and he was the first broadcast journalist to receive the award.
Today:
Palmer officially joined the Today cast as news anchor on September 27, 1982, replacing Chris Wallace, who had read the news and served as Bryant Gumbel and Jane Pauley's Washington co-anchor. The team of Gumbel, Pauley, Palmer, Willard Scott, and Gene Shalit helped take The Today Show to the top of the ratings in 1986, where it stayed until the end of the decade. In the late 1980s, Palmer was the primary substitute co-host of Today on days when Gumbel was away.
Post Today:
After serving as Today news anchor for seven years, Palmer was abruptly replaced by Deborah Norville in September 1989, and was moved to Norville's old position at NBC News at Sunrise. WTVJ, then the NBC owned-and-operated television station in Miami, offered Palmer the lead local news anchor chair in late 1989, but Palmer turned down the opportunity. Palmer left NBC News in March 1990 to anchor a syndicated program, Instant Recall. After that show was canceled, Palmer joined the Christian Science Monitor in December 1991 as anchor of Monitor Channel's short-lived World Monitor newscast. He later served as Washington correspondent for Monitor Radio.
In 1994, NBC News Washington bureau chief Tim Russert and NBC News president Andrew Lack invited Palmer to return to the network as a Washington correspondent, and Palmer accepted. He was soon back on familiar ground, serving as White House correspondent for the weekend edition of NBC Nightly News and an occasional substitute news anchor for The Today Show. He retired from NBC News in January 2002.
Palmer was host of The Informed Citizen and The Prudent Advisor on Retirement Living TV.

Overseas Press Club Award and a National Emmy Award for his reporting on the famine in Africa
National Headliners Award for coverage of the fighting in Lebanon
Emmy for his reporting on America’s space program
The “Distinguished Service in Broadcasting Award” presented by College of Journalism at the University of Georgia.

He was also the recipient of several honorary Doctorate degrees.

Palmer was born in Kingsport, Tennessee. Palmer was a graduate of Northwestern University and obtained a master's degree from Columbia University. Palmer died at the age of 77 on August 3, 2013 in Washington, D.C. from pulmonary fibrosis. He is survived by his wife Nancy and three grown daughters.
