Acting on a tip from an informant whose identity has never been conclusively established, Nazi police discovered the group hidden behind a movable bookcase in a concealed apartment above a spice warehouse. All eight people arrested were deported to Nazi concentration camps. Anne Frank died at Bergen-Belsen concentration camp in February or March 1945 — just weeks before its liberation. Her diary was recovered from the hiding place and published posthumously by her father Otto Frank, the only member of the group to survive. The Diary of a Young Girl has since been translated into over 70 languages and is one of the most widely read books in history.

The Revenue Cutter Service was the only armed maritime presence of the United States for the first eight years of the country's existence. It later merged with the U.S. Life-Saving Service in 1915 to form the modern United States Coast Guard. Today, the Coast Guard is one of America's five armed services, responsible for maritime law enforcement, search and rescue, environmental protection, port security, and national defense. August 4 is observed annually as U.S. Coast Guard Day to honour the service's founding and its personnel.

The Peridot is one of the few gemstones that forms in only one colour — green — with its shade ranging from yellow-green to olive depending on iron content. Unlike most gemstones that form in the Earth's crust, Peridot originates deep in the Earth's mantle and is brought to the surface by volcanic activity. It has also been found in meteorites and in samples brought back from the Moon. The Peridot is associated with peace, good luck, strength, and prosperity. The birth flower for August 4 is the Gladiolus — also called the sword lily — which symbolizes strength of character and moral integrity.
