one of the people we are highlighting is ralph behr who was the inventor of the world's first video gamebegan the video game revolution, which we have now. his prototype that was developed in the 1960's was eventually purchased by magnavox that they turned into the magnavox odyssey, which became the first commercially produced video game. the magnavox odyssey was the precursor to pong and pac man and all of the video games that are on the market today. one of the many authors we have in the exhibit is a first edition copy of rachel carson's "silent spring" that was published in the early 1960's. this book brought national attention to the plight and problems caused by the pesticide d.d.t., which in turn, kicked off the modern environmental movement, which mrs. johnson, during her time in the white house and afterwards, had championed this movement when she promoted programs like highway beautification. she started the lady bird johnson wildfire center here in austin. and other environmental type programs. >> ladies and gentlemen, the beatles!
