Alois Senefelder

Died 26 Feb 1834 at age 62 (born 6 Nov 1771).Johann Nepomuk Franz Alois Senefelder was a German inventor who developed lithography. To publish his own work, he needed a less expensive and more efficient printing alternative to relief printed hand set type or etched plates. His invention was the biggest revolution in the printing industry since Johannes Gutenberg's movable type. Today photo lithography is used to print magazines and books, but the original process of drawing by hand on litho stones still exists in the fine art world. The traditional surface for lithography is Bavarian limestone, regrained by hand for each use. The principle is simple: oil based printing ink and water repel each other. The image is drawn with greasy crayon and chemically treated. The image areas of the stone accept ink and undrawn areas will reject it.

Leaving Dan In My Will

A lawyer meets with the family of a recently deceased millionaire for the reading of the will.
'To my loving wife, Rose, who always stood by me, I leave the house and $2 million,' the attorney reads.
'To my darling daughter, Jessica, who looked after me in sickness and kept the business going, I leave the yacht, the business and $1 million.'
'And finally,' the lawyer concludes, 'to my cousin Dan, who hated me, argued with me and thought I would never mention him in my will. Well, you were wrong. Hi Dan!'
