He was an internationally respected referee who was often used in the early days of European club competitions and at football world championships.
The highlight of Dusch's career began with his appearances at the FIFA World Cups 1958 in Sweden and 1962 in Chile.
This result was not only the Brazilians' only loss of a point in the tournament but also their first goalless game at a World Cup.
The highlight here was the final between Brazil and Sweden, in which the South Americans secured their first world championship title with a 5-2 victory over the hosts.
At the 1962 World Cup in Chile, Dusch officiated the group game in which the USSR defeated the Yugoslavian national team 2-0.
