Strong teacher from the Fifties in Rotterdam, Netherlands

To me this is an amazing picture from a long time ago in Rotterdam, The Netherlands. We see a strong male teacher with a kid that is clearly under his authority.

This basically doesnt exist anymore, most teachers now are female (not complaining, just observation), and the men are also different these days...

And also on a lot of schools there is chaos, difficult to control the kids, I wonder if that would happen with teacher like the one on the picture..
