Why did the slave go to college?
So he could pickup his Master's degree.
Andrew Smith HallidieDied 24 Apr 1900 at age 64 (born 16 Mar 1836).English-American engineer and inventor who built the cable car system first used on the steep hills of San Francisco streets (1 Aug 1873). Streetcars on rails were fitted with a mechanical device that gripped an underground endless moving cable to travel and released to stop. The cable passed around pulleys and was driven by a large wheel at an engine house. He had learned the business of making wire rope from his father before moving to the U.S. (1853), where he designed and built wire suspension bridges and flumes. He began manufacturing wire rope in 1857. Hallidie also developed a method of moving freight over canyons using an endless wire rope, and inventions for the transmission of power with wire rope, which seeded his idea for cable cars.« |
