John's and Nils's father Olof Ericsson who worked as the supervisor for a mine in Wermelandia had lost money in speculations and had to move his family from Wermelandia to Forsvik in 1810. There he worked as a 'director of blastings' during the excavation of the Swedish G?ta Canal. The extraordinary skills of the two brothers were discovered by Baltzar von Platen, the architect of the G?ta Canal. The two brothers were dubbed cadets of mechanics of the Swedish Royal Navy and engaged as trainees at the canal enterprise. At the age of fourteen, John was already working independently as a surveyor. His assistant had to carry a footstool for him to reach the instruments during surveying work.
