Though bulbs brought Edison his fame
As well as lots of gravy,
The man we really ought to blame
Is our Sir Humphry Davy.
The 19th century two years old,
He set a current flowing,
Through platinum, which cost much gold,
And left the metal glowing.
Now all around see bulbs ablaze,
Canary Wharf, or cottage . . .
Sir Humphry’s legacy these days
Is just a mess of wattage.
