Benjamin Franklin's Work in London.jpg
Benjamin Franklin]], American electrician, printer, and diplomat, spent many years on Craven Street. He lived at No. 7 between 1772 and 1775 and at No. 36 from 1757-1762 and again from 1764-1772. During these years, Franklin popularized the study of electricity, performed experiments, and served as an advisor on lightning conductors.

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.

Georgetown, Colorado, on South Clear Creek at east end of 6th Street

Dedication: July 1999 - IEEE Denver Section Electric generating plants, through their high-voltage lines, provided critical power to the isolated mines in this region. Georgetown, completed in 1900, was unusual in employing both steam and water power. Its owner, United Light and Power Company, was a pioneer in using three-phase, 60-Hertz alternating current and in being interconnected with other utilities.
