Two men went bear hunting. While one stayed in the cabin, the other went out looking for a bear.

He soon found a huge bear, shot at it but only wounded it. The enraged bear charged toward him, he dropped his rifle and started running for the cabin as fast as he could.

He ran pretty fast but the bear was just a little faster and gained on him with every step.

Just as he reached the open cabin door, he tripped and fell flat.

Too close behind to stop, the bear tripped over him and went rolling into the cabin.

The man jumped up, closed the cabin door and yelled to his friend inside, "You skin this one while I go and get another!"

Valdemar Poulsen

Born 23 Nov 1869; died 23 Jul 1942 at age 72.Danish engineer who in 1903 developed the first device for generating continuous radio waves, thus aiding the development of radio broadcasting. His arc transmitter increased the frequency range of Duddell's Singing Arc (1900) from the audio range to radio waves, enabling speech to be transmitted up to a radius of 150 miles. By 1920 the Poulsen Arc transmitter was as powerful as 1000kW with ranges of up to 2,500 miles. An earlier invention was the Telegraphone, for which he filed a patent in Denmark on 1 Dec 1898. This was the first device in history to use magnetic sound recording, although this invention remained commercially impractical due to low sound output until the advent of vacuum tube amplifiers in the 1930s.[Biog. Dict. of the Hist. of Tech. gives date of death 23 Jul 1942. DSB and EB give Jul 1942.]
