It's a UK publication so influences will be quite different to the US.

Beaumont Newhalls "History of Photography" was highly biased in it's US viewpoint to the extent that Peter Turner wrote a "History of POhotography" with a more European/'UK bias which was published in the UK.

So there will be big differences in opinions depending on the photo culture you've been steeped in.

I'd add Robert Adams and Robert Misrach, John Blakemore and Ray Moore quite high in that list.
