July 30th Celebrated History


The Town of Baltimore is founded. The great port city along the Patapsco River was central to the Revolutionary War. Named after 1st Baron Baltimore, Baltimore’s first colonial governor was the baron’s second son, Leonard Calvert. Not only was the great city home to poet Edgar Allan Poe, but others like Thurgood Marshall and Babe Ruth also called it home. Baltimore served as the backdrop for the battle that inspired the Star-Spangled Banner, too.


Premiering at Grauman’s Chinese Theater, Walt Disney’s first technicolor short film, Flowers and Trees, later earned a nod from the Academy of Motion Pictures Arts and Sciences.


“In God We Trust” replaces “E Pluribus Unum” as the motto of the United States. President Dwight D. Eisenhower signed the measure into law. While E Pluribus Unum still appears on many U.S. coins and paper bills today, it had been the country’s unofficial motto since 1776. The phrases began appearing together on coins as early as 1861. However, the phrases appeared off and on until 1908 when In God We Trust became a permanent fixture on coins. In 1955, Congress approved adding the phrase to paper money, too.


At 7821 kilometers (4860 miles), the longest national highway in the world opens. Called the Trans-Canada Highway, it begins at Douglas Street and Dallas Road in Victoria, British Columbia, and terminates at St. Johns in Newfoundland and Labrador.


Apollo 15 made history when the first lunar rover (also known as a moon buggy) landed on the moon. The next day, Astronauts David Scott and James Irwin became the first humans to drive on the lunar surface.
