Blue plaque blues

Blue plaque spotting is one of the mind-broadening pleasures of British life. A walk to the dentist can be transformed into a serendipitous encounter with a forgotten genius from the past. ‘Luke Howard, 1772–1864, Namer of Clouds, lived and died here,’ says the blue plaque on 7 Bruce Grove, Tottenham. Even if you’ve never heard of Luke Howard, you instantly take a liking to him — and never again will you hear the word ‘cumulonimbus’ without thinking of him. ‘Lived here’ is the key: you’re passing the very house where the person woke up for breakfast each day, and the intimacy of that is what makes the encounter so much more affecting than merely reading about him or passing a statue of him.

But do you get the feeling that plaques are more ubiquitous, and therefore less frisson–inducing, than they used to be? They seem to be popping up all over the place.
