This was found in Jakobstad's history, volume #3, page 218-220, concerning the Sunday school of Jakobstad.

Through an edict of 19 January 1842, orders were given that Sunday schools for apprentices and journeymen in Christianity and maths should be opened in most towns in Finland, so such a school was also opened in Jakobstad. According to a decree by the governor of Finland of 31 December 1843, the school examination was held twice a year with the pupils.

The school was closed when schools from Vasa were moved to Jakobstad, but reopened in the 1860s.

The Sunday school was under the direction of Gustaf Borg, rector August Höckert, and pharmacist V. Schauman, councilman E.J. Björkman, and businessman P.G. Böckelman and tailor A.F Engström in the 1870s.

Gustaf was 20 years old when he received his diploma on 14 November 1887.

Gustaf Westerholm, the master painter, liked to experiment with many ideas and inventions. A patent for a ventilated pole base was registered in 1912 at the patent office. It was not the success he had hoped. He described the invention:

"My invention was about ventilating and holding a telephone pole or telegraph pole and similar wooden poles, or any material which is easily damaged by rot. The invention is a hollow column with foot, sides and head. Constructed so that when the pole is placed inside this hollow column, the column keeps the pole away from the moisture in the ground. Furthermore, there will be room for air left between the column and the pole..."
