A pub quiz [Answered]

I don’t know who the depicted people are, so for lack of a sensible clue I concocted some sort of pub quiz. When asked for a person’s name, always choose the surname.

Writer of a story about a Dr. and a Mr.
Capital of a country whose name means ‘depths’.
Country that gained independence from another country that is (now) 9.4 times as large as its breakaway neighbour.
Woman who had a computer language named for her.
Foremost 20th century writer of ‘weird’ fiction.
Brazilian seaside resort that I’ve heard of thanks to Astrud Gilberto.
Man who found a way to reduce multiplication to addition (and division to subtraction).
Those water-spouting monsters we have seen here before.
Town where some chap nailed a large number of statements to a door.
The study of knowledge.
Painter of Polynesian women.

I’m sure you know what to do with the answers. The second image is meant to make the actual search a little easier. Street View image please. Good luck!

Now, that Google has corrected me, I have to check what I guessed wrong 

nice puzzle

i lost time because i used the country instead of its capital, so clumsy (dumb?) of me!

I couldn't get answer for #3 and got wrong answer for #7. However I reached the spot with a bit of hint from a birdie.

A drink on the house for all who completed the pub quiz!
