Deddes, Evert Jan.
This photo was taken around his 80th. birthday in 1916, when his grand daughter made a biography to celebrate this date.
During a 2010 cruise on the Prinsendam I came in contact with his Great Grand son who loaned me this biography. With a BIG thank you to Mr. Max van der Poll, great grandson of Captain. Deddes for the permission to put it on line.
