The picture above was probably taken around 1911. I don't really have any other biographical info on him, but I do have a couple of pictures from later in life. The one on the left is of him pedalling petro, and the one on the right is one of him standing with a hat on.
He lived to be 89 years old, and died on 21 May 1955 in Sneek.
