John Henry Holmes - Unknown Savior of the Ozone Layer

In Ancient Greece
Thales of Miletus
Made a distinguished discovery;
Rubbing fur
Caused two objects
To attract
One another.

In 1660 Italy
Otto von Guericke
Of electrostatic generator fame,
Discerned -
Forms of Electricity
Can be positive
Or negative.

The prominent 20th century
War of currents
Ended in a draw:
Thomas Edison
Won direct currents,
George Westinghouse
Won alternating currents.
Energy distributed evenly.

But, in Newcastle England
Unknown savior of the ozone layer
John Henry Holmes
Invented the simple light switch.
Feel the attraction, one to other,
Veer toward the positive,
Win the real energy war,
Honor the light switch!

(Three cheers for the light switch. Hip! Hip! Hello, Hello, Excuse me.. someone put the lights out and I wasn't finished typing.)
