July 7th in history:
On this date in 1958, President Eisenhower signed the Alaska Statehood Act, making Alaska the 49th state – and the biggest state in size. Alaska was admitted officially the following January.
Construction of Boulder Dam (now Hoover Dam) began on July 7th, 1930. At the time it was completed, the 700-foot high dam on the Colorado River was the largest concrete structure in the world.
Was Boulder Dam “the greatest thing since sliced bread”? Maybe not, but pre-sliced bread was considered a big thing when it was introduced on July 7th, 1928, by a bakery in Chillicothe, Missouri. That innovation was advertised as the “greatest forward step” in baking since wrapped bread.
