On 10 January, at 16:00, the Chairman of the UN Preparatory Commission and Colombian delegate to the UN Eduardo Zuleta delivered a speech, announcing the opening of the first session of the UN General Assembly. 400 journalists and 300 guests attended the event in the Central Hall.
British Prime Minister Clement Attlee said: “Looking back on past years, we can trace the origins of the late war to acts of aggression, the significance of which was not fully realized at the time. [...] In the last five years, the aggression of Hitler in Europe drew eventually into the contest men from all continents and from the islands of the sea. It should make us all realise that the welfare of every one of us is bound up with the welfare of the world as a whole, and that we are truly all members one of another”.
A Soviet delegation was represented by Andrey Gromyko, the Extraordinary and Authorised Ambassador to the US, and the USSR’s future permanent envoy to the UN.
During the first UN session, it was Gromyko who called for nominating then-Norwegian Foreign Minister Trygve Lie for the post of the UN General Assembly president. A secret voting (28 against 23), however, saw Belgian Foreign Minister Paul-Henri Spaak taking office.
The first resolution of the UN General Assembly pertained to the peaceful use of atomic energy and the elimination of nuclear arms as well as other types of weapons of mass destruction.
“Today as never before the world is united”, Attlee concluded.
