- Ferd Crone was the mayor of Leeuwarden from 1982 to 1990.
- He was awarded the Elfstedenkruisje in 1986 for his participation in the Elfstedentocht of 1986.
- The Elfstedentocht is a 200 km (124 mi) long ice skating race held in the Netherlands.
- The race is only held when the ice on the canals and lakes is thick enough to support the weight of the skaters.
- The Elfstedenkruisje is a medal awarded to those who complete the Elfstedentocht.
The other possible answers are:
- Henk Angenent
- Evert van Benthem
- Rintje Ritsma
