The Stockholm Games are considered among the most successful Olympics ever. Much of the credit for the Games' success is given to Swedish King Gustav who presided over them. Renowned architect Torben Grut designed a 31,000 seat Olympic stadium, while an English expert, Charles Perry, supervised the layout of the running track. To insure high standards of competition, the number of sports were limited to fourteen . At the King's wish, women's swimming was introduced, despite opposition from the founding fathers of the Olympic movement. The introduction of neutral officiating and international rules contributed to a friendly atmosphere.
