Question 1:
Who was the inventor of the vacuum cleaner?
Answer:
Ives W. McGaffey devised the first vacuum cleaner in 1869. He called his crank-operated machine The Whirlwind. In 1901 Englishman Hubert Cecil Booth invented a large, horse-drawn unit powered by a gasoline engine, with long hoses fed through the windows. J. Murray Spangler of Canton, Ohio, invented the first functioning portable electric vacuum cleaner in 1907. It was built by the Hoover Company of New Berlin, Ohio, who rolled out their first electric Model O in 1908.
Question 2:
Who invented blue jeans?
Answer:
Jacob Davis, a Nevada tailor, came up with the idea of placing metal rivets on the denim at the points of strain. In 1873 he and Levi Strauss patented the process.
Question 3:
Did Elisha Graves Otis invent the elevator?
Answer:
No, hoists already existed. But in 1853, Otis invented the elevator brake so that they wouldn't fall - obviously, a necessary improvement.
Question 4:
Who invented the computer mouse?
Answer:
Among Douglas C. Engelbart's two dozen patents, is one for a "K-Y Position for a Display System," which is a prototype for the mouse. Although the device was invented in 1968, Engelbart's brainchild was not popularized until Apple used it in 1984.
Interesting. I'll bet Davis and Strauss never imagined that ripped jeans would be high fashion.

ReplyDeleteThe gasoline vacuum cleaner sounds like something only used in direst of circumstances. I am so glad they have improved to what they are today.
ReplyDeleteI agree, it must have seemed a wonderful piece of technology back then and they certainly have evolved. Thanks Rose :)
