More than a century ago, Cripps successfully employed the direct and complete division of the anal sphincters as a means of approaching the lower rectum and anal canal, and reported on a series of 36 patients who had been treated in that fashion. Cripps was pleasantly surprised to find good fecal continence in over two-thirds of the patients during later follow-ups, despite the fact that the divided sphincters had not been repaired. The transsphincteric procedure was largely forgotten in subsequent years, however, and only the parasacral proctotomy of Kraske, which spared the anal sphincters, can be said to have gained an established place in the" surgical armamentarium. " It remained for York Mason to redirect the attention of the surgical community to the great potential of the trans sphincteric approach and the excellent continence that can be achieved through adequate repair of the divided sphincters. Having recognized the outstanding practical value of this procedure, we felt it necessary to define more precisely the anatomical prerequisites that would ensure minimum operative bleeding, and to bring the procedure more in line with current knowledge of normal continence and defecation. Dr. A. Huber, in consultation with the director of the Institute for Clinical Anatomy of our surgical department, Prof. A. von Hochstetter, did many months of dissection work on fresh anatomic preparations in an effort to explore and refine the various aspects of the trans sphincteric ap proach.

The present volume contains articles pertaining to a wide variety of sub- jects such as conformal and quasi conformal mappings and related extremal problems, Riemann surfaces, meromorphic functions, subharmonic functions, approximation and interpolation, and other questions of complex analysis. These contributions by mathematicians from allover the world express con- sideration and friendship for Albert Pfluger. They reflect the wide range of his interests. Albert Pfluger was born on 13 October 1907 in Oensingen (Kanton Solothurn) as the oldest son of a Swiss farmer. After a classical education he studied Mathematics at the ETH-Zurich. Among his teachers were Hopf, Plancherel, P6lya and Saxer. P6lya was his Ph.D. adviser. After some teaching at high schools (Gymnasien), he became professor at the University of Fribourg, and a few years later (1943) he was appointed as successor of P6lya at the ETH. He retired in 1978, but has always remained very active in research. Pfluger's lectures were highly appreciated by the students. His vivid and clear teaching stimulated and challenged them to independent thinking. Many of his Ph.D. students are now themselves teaching in universities.His main research relates to the following fields: entire functions, Riemann surfaces, quasi conformal mappings, schlicht functions. (See list of publica- tions.) He collaborated with several mathematical colleagues, in particular with Rolf Nevanlinna, who taught parallel to him at the University of Zurich. In 1973 Pfluger was nominated foreign member of the Finnish Academy of Sciences.
