Geran was the first player from the United States to make the NHL, starting with the
Montreal Wanderers in the NHL's inaugural season,
1917–18. The Wanderers arena, the
Westmount Arena, burnt down on January 2, 1918, and with no alternative the team folded after six games; Geran had played in four of them but recorded no points. In
1921–22 Geran signed with
Français Volants, a team based in
Paris, becoming the first American to play in France. He scored 88 goals in eight games there. He returned to the US and spent the next several years playing in Boston in the
United States Amateur Hockey Association, and in 1925 went back to the NHL as he signed with the
Boston Bruins. The manager of the Bruins was
Art Ross, who had been Geran's teammate on the Wanderers and a good friend. Geran played 33 games in
1925–26, scoring five goals and one assist, and left the league after that. In 37 career NHL games, he scored five goals and six points. Geran's first two goals as a Bruin came in the same game, his team's 5-3 loss to the Pittsburgh Pirates on December 11, 1925. He joined the
St. Paul Saints of the new
American Hockey Association, and spent one year there. He returned to France in 1932 and played a final season of hockey with
Racing Club de France before retiring. After retiring he took part in a 1941 effort to unionize hockey players, but that did not lead to anything, and his last known work was in 1962 as a federal worker in New York City. ==International career==
