August 10 – The Swedish warship Vasa sank on its maiden voyage in Stockholm harbor on August 10, 1628, after capsizing due to a gust of wind, causing about 30 deaths among 150 on board. Nearly 400 years later, DNA testing revealed that a person initially thought to be male, named "Gustav," was actually female. This discovery, and others, provide insights into 17th-century Sweden, according to Vasa Museum director Fred Hocker. The Vasa was salvaged between 1958 and 1961 and is now displayed at the Vasa Museum. DNA studies in 2004 identified 15 adults and remains of at least two others. Further genetic testing will reveal more about the Vasa's crew.[1]
