What: Edsger W. Dijkstra
The Explorer is the Person Who is Lost
Also, Edsger W. Dijkstra:
Looking closely at himself he realized that if he wrote about things they would appreciate at the MC in Amsterdam his colleagues in Eindhoven would not understand; if he wrote about things they would like in Eindhoven, his former colleagues in Amsterdam would look down on him. He then decided to write only for himself, and in this way the EWDs were born.
