in
Antarctica and became an internationally renowned
meteorologist. He was instrumental in restoring

National Academy of Sciences are
named in his honor. He was a prolific writer/author.
After his return from the Antarctic he lived in Brussels, analyzing
the results of the expedition at the
Royal Observatory of Belgium, at

1919. In 1915 he became an American citizen.
In 1920 he returned to newly independent Poland. Prime minister
Paderewski had offered him the
position of minister of education, but he refused and became
professor of geophysics and meteorology at
Jan Kazimierz University. He was very
active in research (144 papers were published by him and his
assistants) and involved in the
International
Union of Geodesy and Geophysics. In 1939 he travelled with his
wife to the United States to attend a conference of the
International Union of Geodesy and Geophysics, when the Soviet
Union and Nazi Germany invaded Poland. They never managed to return
to Poland and lost all their possessions.
Arctowski joined
The Explorers Club in New York in 1920. He
accepted a position as a research associate at the
Smithsonian and continued doing
research until his death, even when he was obliged to resign in
1950 due to an illness.
The
Antarctic Treaty and related
agreements, collectively called the
Antarctic Treaty
System or
ATS,
regulate international relations with respect
to Antarctica, Earth´s only continent without a native human
population. For the purposes of the treaty system, Antarctica is
defined as all of the land and ice shelves south
of 60°S latitude. The treaty, entering into force in 1961 and
currently having 50 signatory nations, sets aside Antarctica as a
scientific preserve, establishes freedom of scientific
investigation and bans military activity on that continent.
The treaty was the first arms control agreement
established during the Cold War. The Antarctic
Treaty Secretariat headquarters have been located
in Buenos Aires, Argentina, since September 2004.
