Boulder Dam construction begins |
Boulder Dam construction begins In 1930, construction began on the site infrastructure for construction of Boulder Dam (Hoover Dam). What had taken decades to come to a political resolution, took only five years more to become a reality. It took the labour of 21,000 men to produce what is now the second-highest dam in the country. The concrete gravity-arch dam on the Colorado River bewteen Nevada and Arizona, impounds Lake Mead, the largest U.S. reservioir. It generates electricity, supplies water to California cities and irrigation to support farming, as well as flood control. Bids for construction were opened on 11 Mar 1931, and awarded to Six Companies, Inc., for $48,890,995. On 6 Jun 1933, the first concrete was poured. It was dedicated on 30 Sep 1935, by President Franklin D. Roosevelt. |

Sir Arthur Conan Doyle |
death Sir Arthur Conan Doyle Died 7 Jul 1930 at age 71 (born 22 May 1859). Scottish author and physician whose fictional detective, Sherlock Holmes, emulates the scientist, diligently searching through data and to make sense of it. “It is a capital mistake to theorize before one has data.” His medical degree was awarded at the University of Edinburgh, where he studied under noted surgeon Joseph Bell. After serving as the doctor on an Arctic whaling ship, he practiced in England for a short time as a physician, with little income. So he turned to writing. He was active as a social reformer, and spoke to the Committee on the Daylight Saving Bill in 1908 advocating its adoption. Later in life he was a convert to spiritualism, and requested burial in an upright position in the garden of his home. |
