en.wikipedia.org/wiki/Arkady_Shevchenko

The infobox says Shevchenko died in Washington, D.C., but contemporary obituary coverage places his death in Bethesda, Maryland.

• The Los Angeles Times obituary states that "Shevchenko died Feb. 28 in his home in Bethesda, Md."
• The Washington Post obituary likewise reported that he "died of a heart attack Feb. 28 at his home in Bethesda."

So the article's listed death place, Washington, D.C., U.S., is inconsistent with contemporaneous reporting and appears to be incorrect.

Official UN sources from Shevchenko's time give his title as Under-Secretary-General for Political and Security Council Affairs.

• A UN appointment record for Shevchenko states that he assumed the post as "Under-Secretary-General for Political and Security Council Affairs."
• The UN Yearbook's 1974 organizational roster likewise lists "Department of Political and Security Council Affairs — Under-Secretary-General: Arkady N. Shevchenko."

So the article's infobox title, "United Nations Under-Secretary-General for Political Affairs," is anachronistic and does not match the historical name of the office Shevchenko actually held.
