Milestones:Benjamin Franklin's work in London, 1757-1775
Franklin, considered one of the founders of modern Physics, was already a famous scientist when he arrived at Craven Street in 1757. He resided there for 16 years.
In the room behind his parlor, Franklin constructed a laboratory for his research. Here he continued his electrical experiments. He proved that electricity has a positive and a negative charge, invented an improved generator and storage batteries. Franklin had proved that lightning is electrical. He had flown metal-tipped kites during thunderstorms and "captured the fire of heaven". He continued these experiments, sending kites aloft along the Thames during thunderstorms. By experimenting with different metals and shapes he was able to perfect his famous lightning rod conductor. This was such a success that Lightning Rods were placed on St. James's Palace (greatly to the annoyance of George III) and on the other great State buildings, churches and cathedrals in London.
At Craven Street, Franklin perfected his famous Stove, which is still in wide use today. It burns its own smoke and saves fuel.
During a hot London summer Franklin invented the Air Bath, the forerunner of Air Conditioning.
