Book excerpt: Over the last half-century, as UNCITRAL official, professor, arbitrator and father of the Willem C. Vis Arbitration Moot, Eric Bergsten has been at the forefront of progress in international commercial arbitration. Now, on the occasion of his eightieth birthday, the international arbitration and sales law community has gathered to honour him with this substantial collection of new essays on the many facets of the field to which he continues to bring his intellect, integrity, inquisitive nature, eye for detail, precision, and commitment to public service. Celebrating the long-standing and sustained contribution Eric Bergsten has made in international commercial law, international arbitration, and legal education, more than fifty colleagues - among them quite a few of the best-known arbitrators and arbitration academics in the world - present 45 pieces that, individually both engaging and incisive, collectively present a thorough and far-reaching account of the state of the field today, with contributions covering international sales law, commercial law, commercial arbitration, and investment arbitration. In addition, nine essays on issues in legal education mirror the great importance of the renowned Willem C. Vis International Commercial Arbitration Moot, Eric's Vienna project which has offered a life-changing experience for so many young lawyers from all over the world.
