How many deaths occured while building the hoover dam?

Question

Name the first and the last people to die building the hoover dam.

Answer 1

112 men were killed during the construction of Hoover Dam on the Nevada-Arizona border (the "official" number was 98, but others had died from causes more difficult to identify -- or easier to ignore -- like by carbon monoxide poisoning):  The first was a surveyor, J.G. Tierney, who drowned on December 20, 1922, and the last was his son, Patrick Tierney, who drowned on December 20, 1935 -- 13 years to the day after his father.
