Heinrich HertzBorn 22 Feb 1857; died 1 Jan 1894 at age 36. Heinrich Rudolf Hertz was a German physicist who was the first to broadcast and receive radio waves. He studied under Kirchhoff and Helmholtz in Berlin, and became professor at Bonn in 1889. His main work was on electromagnetic waves (1887). Hertz generated electric waves by means of the oscillatory discharge of a condenser through a loop provided with a spark gap, and then detecting them with a similar type of circuit. Hertz's condenser was a pair of metal rods, placed end to end with a small gap for a spark between them. Hertz was also the first to discover the photoelectric effect. The unit of frequency - one cycle per second - is named after him. Hertz died of blood poisoning in 1894 at the age of 37. |

Returning home from work, a blonde was shocked to find her house ransacked and burglarized. She telephoned the police at once a nd reported the crime. The police dispatcher broadcast the call on the radio, and a K-9 unit, patrolling nearby, was the first to respond.
As the K-9 officer approached the house with his dog on a leash, the blonde ran out on the porch, shuddered at the sight of the cop and his dog, then sat down on the steps. Putting her face in her hands, she moaned, 'I come home to find all my possessions stolen. I call the police for help, and what do they do? They send me a BLIND policeman!'
