Quirinus Harder

Quirinus Johan Harder (13 October 1801 in Rotterdam – 21 October 1880 in Vlissingen[1][2]) was a Dutch architect best known for having designed a large number of lighthouses. He worked as a structural engineer for the Loodswezen, the Dutch organization overseeing all maritime pilots. Harder's lighthouses were made of cast iron, a new material at the time, which allowed for segmented fabrication and construction.[3]

gollark: I have not.
gollark: Not really, I just won't get one for ages.
gollark: The inconvenient thing about the internet is that there's tons of sometimes-contradictory information on everything ever, and it's hard to find out about subjects which are new for you.
gollark: Based on what happened with the people who had to selfisolate there will be actual teachers there, and we have pretty small classes so it should be okay.
gollark: My school is apparently doing two weeks or so online when it starts back up again (in a few days?).
