Rudolf Iselin

Rudolf Iselin (date of birth unknown) was a Swiss footballer who played as midfielder in the late 1890s.

Iselin joined FC Basel's first team during their 1896–97 season. The official Swiss national championship had not yet been called into life and so the team played only friendly games. Iselin played his first game for the club in the home game on 8 November 1896 as Basel were defeated 1–2 by Grasshopper Club. Iselin played in five of the club's seven friendly games that season. In the following season he played in six of their ten friendly games.

The first edition of the official Swiss championship was played in the 1898–99 season as a knock out competition. Basel played against Old Boys in the central group semi-final. Iselin played his league debut for the club in this home game at the Landhof on 13 November 1898. It ended in 1–1 draw with their local rivals. It therefore required a replay. This replay was held in the Stadion Schützenmatte on 18 December 1898. This was also drawn 2–2, despite an agreed two times 20 minutes extra time. Because the Old Boys complained that the first FCB goal scored by Rudolf La Roche in the 10th minute had been scored by hand, they protested and the SFA had to deal with the matter. Subsequently, the protest was approved and awarded - and the disputed goal was simply deducted from the score to give the final result. Thus the Old Boys became the first forfait winners in Swiss football history. The Old Boys advanced to the finals, but the Anglo-American Club Zürich became Swiss champions.

A curiosity in this 1898–99 season was the game in Zürich on 5 March 1899. The majority of them English students, had formed a club and the members of the Anglo-American Club even attended the founder meeting of the Swiss Football Association (ASF-SFV) in April 1895. They had found a place to play their games, although the Zurich commons was by no means ideal. It was often that the players found the grounds very sludgy or with freshly raised molehills. But at least, it was a homestead that was soon called "Anglo-Platz". Suddenly the announcement: "By decree of the military directorate of the canton of Zurich it is forbidden until further notice to play on the military training area Allmend". In the age of mobile communications, a short-term postponement may not attract much attention. But at the end of the 19th century constant accessibility wasn't even wishful thinking. The following could be read about the game against FC Basel which was brought forward from the afternoon to the morning: “As a result, the Anglos, who were only partially able to notify their people, started the game with only seven men. Only during the course of the game was the team completed to the full eleven. There were also replacements in Basel's team, because some players did not arrive until a later train. The appointed referee was not there because he been scheduled for the afternoon. The crowd consisted of approximately 10 to 20 spectators. Under such circumstances, such an important match should not have been played." Despite all the obstacles: The game became a demonstration of the superiority of the British players from Zurich. The Anglo American Football Club won the match 10–0, with their center forward Robert Collinson alone scoring 8 goals. By then, at the latest, it was clear that the Anglos would be unstoppable on their way to the title.

In his three seasons with the club Iselin appeared in at least 18 games for Basel without scoring a goal. Two of these games were in the Swiss Serie A and the other 16 appearances were in friendly games.
