Who is the mysterious person in the picture?

Sir Joseph Wilson Swan

Died 27 May 1914 at age 85 (born 31 Oct 1828). English scientist, chemist, physicist and inventor, born in Sunderland, Yorkshire, who produced an early electric incandescent lamp. He began these experiments in the 1840's and obtained a UK patent covering a partial vacuum, carbon filament incandescent lamp in 1860. Swan's early lamps provided low light output, were short lived, and were operated from battery cells. Low voltage operation required relatively high filament current that necessitated that the power source be co-located near the Swan lamp. He also addressed the problem of photographic print fading and in the mid 1850s some began to experiment with a solution using carbon, perfecting and patenting the process in 1864. Thus Swan invented the dry photographic plate, an important improvement in photography.[Image: pencil drawing by M. Agnes Cohen, 1894.]

Devil at the congregation

One bright, beautiful Sunday morning, everyone in the tiny town of Johnstown got up early and went to the local church. Before the services started, the townspeople were sitting in their pews and talking about their lives and their families.

Suddenly, the Devil himself appeared at the front of the congregation. Everyone started screaming and running for the front entrance, trampling each other in a frantic effort to get away from evil incarnate.

Soon everyone was evacuated from the Church, except for one elderly gentleman who sat calmly in his pew, not moving, seemingly oblivious to the fact that God's ultimate enemy was in his presence. Now this confused Satan a bit, so he walked up to the man and said, "Don't you know who I am?"

The man replied "Yep, sure do."

Satan asked "Aren't you afraid of me?"

"Nope, sure ain't," said the man.

Satan was a little perturbed at this and queried "Why aren't you afraid of me?"

The man calmly replied "Been married to your sister for over 48 years."
