no.1 is credited as the first photograph ever taken.
I like Roger Fenton's Crimea War photographs as seen in no.2.
On a personal level, no.7 really sticks in my mind from that time.

But I am surprised that they did not include the most famous photo that changed the way we look at the world, both figuratively and literally, namely the photo of the earth breaking over the moon's horizon.

"Deaths in the Bible. God - 2,270,365
not including the victims of Noah's flood, Sodom and Gomorrah, or the
many plagues, famines, fiery serpents, etc because no specific numbers
were given. Satan - 10."
