ONE OR TWO REVISIONS NEED TO BE MADE TO THE ARTICLE ON OLIVER LODGE - HERE ARE A FEW LEADS:

LODGE WAS A MAJOR CONTRIBUTOR TO THE EARLY DEVELOPMENT OF WIRELESS TELEGRAPHY - NOT ITS INVENTOR.

LODGE CATEGORICALLY DID NOT INVENT THE VALVE (VACUUM TUBE).

LODGE DID INTRODUCE A SPECIAL PURPOSE SPARK IGNITER. HIS SONS DEVELOPED AND MANUFACTURED THE LODGE SPARK PLUG.

LODGE DID INVENT THE MOVING COIL LOUDSPEAKER.

LODGE DID GIVE A MOST IMPRESSIVE DEMONSTRATION OF THE TRANSMISSION AND DETECTION OF HERTZIAN WAVES IN JUNE 1894 AT THE ROYAL INSTITUTION WHERE HE USED A PRIMITIVE FORM OF THE BRANLY FILINGS TUBE WHICH HE CALLED A COHERER. HE REPEATED HIS LECTURE AND DEMONSTRATIONS AT THE BRITISH ASSOCIATION MEETING AT OXFORD IN AUGUST 1894 WHERE HE MADE GOOD USE OF THE KELVIN MARINE GALVANOMETER LOANED TO HIM BY ALEXANDER MUIRHEAD.

AGAIN, I REPEAT, PLEASE REMOVE ANY SUGGESTION THAT OLIVER LODGE INVENTED THE VALVE(VACUUM TUBE)BECAUSE THIS IS ABSOLUTELY WRONG AND IS ALREADY CAUSING MISINFORMATION TO CIRCULATE.

OLIVER LODGE'S GREATEST CLAIM TO FAME IN THE FIELD OF WIRELESS TELEGRAPHY IS THE TUNED CIRCUIT - WHICH AROSE FROM HIS OWN BRILLIANT EXPERIMENTS AND FROM THE DEEP INSIGHT HE DERIVED FROM THE WORK OF JAMES CLERK MAXWELL.
