The Rosetta Stone is found in the Egyptian village of Rosetta by French Captain Pierre-François Bouchard during Napoleon's Egyptian Campaign.
Captain Pierre-François Bouchard uncovers the Rosetta Stone in Rosetta, Egypt, paving the way to deciphering ancient hieroglyphs.
On July 15, 1799, during Napoleon's Egyptian Campaign, Captain Pierre-François Bouchard uncovered a basalt stone inscribed with parallel texts in three scripts. Known as the Rosetta Stone, it features Greek, Demotic, and hieroglyphic inscriptions. The presence of the Greek text provided scholars with the key they needed to begin deciphering Egyptian hieroglyphs. Over decades, researchers like Jean-François Champollion used the stone's trilingual inscriptions to unlock the ancient language. The discovery marked a turning point in Egyptology, revealing the civilization's history and culture. Today, the Rosetta Stone remains one of the most visited artifacts in the British Museum.

In his book Clinical Psychiatry, Emil Kraepelin gives a name to Alzheimer's disease, naming it after his colleague Alois Alzheimer.
Emil Kraepelin introduces the term Alzheimer's disease in his seminal work Clinical Psychiatry, naming the disorder after his colleague Alois Alzheimer.
In his influential 1910 publication Clinical Psychiatry, German psychiatrist Emil Kraepelin formally designated the neurodegenerative disorder first described by Alois Alzheimer as Alzheimer's disease. Kraepelin's classification distinguished the condition from other forms of senile dementia. He detailed the clinical symptoms of memory loss, cognitive decline, and personality changes observed by Alzheimer. This nomenclature provided a framework for future pathological and clinical research. Alzheimer's disease has since become the most common form of dementia worldwide, affecting millions and driving advances in neuroscience.

The Boeing 367-80, the prototype for both the Boeing 707 and C-135 series, takes its first flight.
The Boeing 367-80 prototype, the basis for the legendary Boeing 707, achieves its maiden flight.
On July 15, 1954, Boeing's Model 367-80 prototype took to the skies for the first time in Renton, Washington. Known as the "Dash 80", this aircraft served as the technological foundation for the iconic Boeing 707 commercial jet and the USAF C-135 Stratolifter. Designed in under two years, the Dash 80 demonstrated the feasibility of jet-powered passenger airliners. Its successful flight ushered in the Jet Age, revolutionizing air travel with higher speeds and greater range. Pan American World Airways would later introduce the 707 on transatlantic routes in 1958. The military variant, the C-135, became a workhorse for aerial refueling and transport. The prototype's innovative design featured sleek swept wings and powerful turbojet engines. Today, the Dash 80 is remembered as a milestone in aviation history.

Space Race: Apollo–Soyuz Test Project features the dual launch of an Apollo spacecraft and a Soyuz spacecraft on the first Soviet-United States human-crewed flight. It was the last launch of both an Apollo spacecraft, and the Saturn family of rockets.
The Apollo–Soyuz Test Project launches, marking the first joint U.S.-Soviet crewed space mission.
On July 15, 1975, NASA’s Apollo and the Soviet Soyuz spacecraft launched on a historic joint mission. The Apollo–Soyuz Test Project marked the first time American and Soviet astronauts docked in orbit. A specially designed docking module connected the two spacecraft, symbolizing a thaw in Cold War relations. During their rendezvous, crew members exchanged gifts and conducted scientific experiments together. The mission represented the final flight of an Apollo spacecraft and the Saturn IB rocket. It laid the groundwork for future international collaborations in space exploration. Engineers and astronauts from both nations gained valuable data on docking and life-support interoperability. The Apollo–Soyuz Test Project remains a milestone in the history of human spaceflight.
