Paul Stern (1892 – 12 June 1948) was an Austrian international bridge player and lawyer, who fled to London in 1938. He was a bidding theorist and administrator who contributed to the early growth of the game. He founded the Austrian Bridge Federation in 1929, and was its first president.
According to his obituary in the Contract Bridge Journal:
Paul Stern - whose "Dr." was a so inseparable part of his name that he signed the most casual post-card with the prefix - was, both in his early life and in his exile, an unforgettable figure. He was tall, burly, irascible, with a voice so rough, a temperament so volatile that half the people who saw him called him a dictator; but with a charm so great, a sweetness so unexpected that even those he castigated seldom bore malice for long.
Stern was a member of the Austria open teams that won the first two European championships, 1932 and 1933, under the auspices of the International Bridge League in Scheveningen, Netherlands, and in London. In 1935 he developed the Vienna System, or Austrian System, the first highly artificial bidding system to achieve international success. Strong hands (equivalent to about 18 or more high-card points using the now-standard Milton Work count) were opened One Notrump; most hands with 11–17 points that lacked a five card spade, heart or diamond suit were opened One Club. Many strong players adopted the Vienna System and Stern remained the leader and an important mentor. He was the non-playing captain when Austria recaptured the European championships (Open category) in 1936 and 1937.
The 1937 IBL Championships doubled as the first world championship tournament, conducted June 1937 in Budapest. In the final, Austria defeated Ely Culbertson's team from the United States by 4,740 points over 96 boards, using the Vienna System against the natural Culbertson system. The result of this match caused a sensation, as did all the previous Culbertson matches. Stern's book on the championships does not mention that there were other teams in the event! The world champions were anchored by Karl Schneider and Hans Jellinek, perhaps the world's strongest pair at the time, with Karl von Blöhdorn, Dr Edward Frischauer, Walter Herbert and Udo von Meissl. (Bridge teams, or teams-of-four, commonly have six players with two on the "bench" at any time.) Culbertson traveled with four players, as usual —Ely and Josephine at one table, Helen Sobel and Charles Vogelhofer at the other— and it was widely thought at the time that this quartet was not America's best. In addition, the Culbertsons were on the verge of divorce, which cannot be good for a bridge partnership.
