1880 – Helen Keller, American author, academic, and activist is born.
Helen Adams Keller was an American author, political activist, and lecturer. She was the first deaf-blind person to earn a bachelor of arts degree. The story of how Keller’s teacher, Anne Sullivan, broke through the isolation imposed by a near complete lack of language, allowing the girl to blossom as she learned to communicate, has become widely known through the dramatic depictions of the play and film The Miracle Worker. Her birthplace in West Tuscumbia, Alabama, is now a museum and sponsors an annual “Helen Keller Day”. Her birthday on June 27 is commemorated as Helen Keller Day in the U.S. state of Pennsylvania and was authorized at the federal level by presidential proclamation by President Jimmy Carter in 1980, the 100th anniversary of her birth.
A prolific author, Keller was well-traveled and outspoken in her convictions. A member of the Socialist Party of America and the Industrial Workers of the World, she campaigned for women’s suffrage, labor rights, socialism, antimilitarism, and other similar causes. She was inducted into the Alabama Women’s Hall of Fame in 1971 and was one of twelve inaugural inductees to the Alabama Writers Hall of Fame on June 8, 2015. Keller proved to the world that deaf people could all learn to communicate and that they could survive in the hearing world. She also taught that deaf people are capable of doing things that hearing people can do. One of the most famous deaf people in history, she is an idol to many deaf people in the world.
1895 – The inaugural run of the Baltimore and Ohio Railroad’s Royal Blue from Washington, D.C., to New York City, the first U.S. passenger train to use electric locomotives.
The Royal Blue was the Baltimore and Ohio Railroad (B&O)’s flagship passenger train between New York City and Washington, D.C., in the United States, beginning in 1890. The Baltimore-based B&O also used the name between 1890 and 1917 for its improved passenger service between New York and Washington launched in the 1890s, collectively dubbed the Royal Blue Line. Using variants such as the Royal Limited and Royal Special for individual Royal Blue trains, the B&O operated the service in partnership with the Reading Railroad and the Central Railroad of New Jersey. Principal intermediate cities served were Philadelphia, Wilmington, and Baltimore. Later, as Europe reeled from the carnage of World War I and connotations of European royalty fell into disfavor, the B&O discreetly omitted the sobriquet Royal Blue Line from its New York passenger service and the Royal Blue disappeared from B&O timetables. Beginning in 1917, former Royal Blue Line trains were renamed: the Royal Limited (inaugurated on May 15, 1898), for example, became the National Limited, continuing west from Washington to St. Louis via Cincinnati. During the Depression, the B&O hearkened back to the halcyon pre-World War I era when it launched a re-christened Royal Blue train between New York and Washington in 1935. The B&O finally discontinued passenger service north of Baltimore on April 26, 1958, and the Royal Blue faded into history.
Railroad historian Herbert Harwood said, in his seminal history of the service, “First conceived in late Victorian times to promote a new railroad line … it was indeed one of the most memorable images in the transportation business, an inspired blend of majesty and mystique … Royal Blue Line … Royal Blue Trains … the Royal Blue all meant different things at different times. But essentially they all symbolized one thing: the B&O’s regal route.” Between the 1890s and World War I, the B&O’s six daily Royal Blue trains providing service between New York and Washington were noted for their luxury, elegant appearance, and speed. The car interiors were paneled in mahogany, had fully enclosed vestibules (instead of open platforms, still widely in use at the time on U.S. railroads), then-modern heating and lighting, and leaded glass windows. The car exteriors were painted a deep “Royal Saxony blue” color with gold leaf trim.
The B&O’s use of electrification instead of steam power in a Baltimore tunnel on the Royal Blue Line, beginning in 1895, marked the first use of electric locomotives by an American railroad and presaged the dawn of practical alternatives to steam power in the 20th century. Spurred by intense competition from the formidable Pennsylvania Railroad, the dominant railroad in the lucrative New York–Washington market since the 1880s, the Royal Blue in its mid-1930s reincarnation was noted for a number of technological innovations, including streamlining and the first non-articulated diesel locomotive on a passenger train in the U.S., a harbinger of the steam locomotive’s eventual demise.
1898 – The first solo circumnavigation of the globe is completed by Joshua Slocum from Briar Island, Nova Scotia.
On April 24, 1895, he set sail from Boston, Massachusetts. In his famous book, Sailing Alone Around the World, now considered a classic of travel literature, he described his departure in the following manner:
“I had resolved on a voyage around the world, and as the wind on the morning of April 24, 1895 was fair, at noon I weighed anchor, set sail, and filled away from Boston, where the Spray had been moored snugly all winter. The twelve o’clock whistles were blowing just as the sloop shot ahead under full sail. A short board was made up the harbor on the port tack, then coming about she stood to seaward, with her boom well off to port, and swung past the ferries with lively heels. A photographer on the outer pier of East Boston got a picture of her as she swept by, her flag at the peak throwing her folds clear. A thrilling pulse beat high in me. My step was light on deck in the crisp air. I felt there could be no turning back, and that I was engaging in an adventure the meaning of which I thoroughly understood.”
After an extended visit to his boyhood home at Brier Island and visiting old haunts on the coast of Nova Scotia, Slocum departed North America at Sambro Island Lighthouse near Halifax, Nova Scotia on July 3, 1895.
Slocum intended to sail eastward around the world, using the Suez Canal, but when he got to Gibraltar he realized that sailing through the southern Mediterranean would be too dangerous for a lone sailor because of the piracy that still went on there at that time. So he decided to sail westward, in the southern hemisphere. He headed to Brazil, and then the Straits of Magellan. At that point he was unable to start across the Pacific for forty days because of a storm. Eventually he made his way to Australia, sailed north along the east coast, crossed the Indian Ocean, rounded the Cape of Good Hope, and then headed back to North America.
Slocum navigated without a chronometer, instead relying on the traditional method of dead reckoning for longitude, which required only a cheap tin clock for approximate time, and noon-sun sights for latitude. On one long passage in the Pacific, Slocum also famously shot a lunar distance observation, decades after these observations had ceased to be commonly employed, which allowed him to check his longitude independently. However, Slocum’s primary method for finding longitude was still dead reckoning; he recorded only one lunar observation during the entire circumnavigation.
Slocum normally sailed the Spray without touching the helm. Due to the length of the sail plan relative to the hull, and the long keel, the Spray was capable of self-steering (unlike faster modern craft), and he balanced it stably on any course relative to the wind by adjusting or reefing the sails and by lashing the helm fast. He sailed 2,000 miles (3,200 km) west across the Pacific without once touching the helm.
More than three years later, on June 27, 1898, he returned to Newport, Rhode Island, having circumnavigated the world, a distance of more than 46,000 miles (74,000 km). Slocum’s return went almost unnoticed. The Spanish–American War, which had begun two months earlier, dominated the headlines. After the end of major hostilities, many American newspapers published articles describing Slocum’s amazing adventure.
2013 – NASA launches the Interface Region Imaging Spectrograph, a space probe to observe the Sun.
The Interface Region Imaging Spectrograph (IRIS) is a NASA solar observation satellite. The mission was funded through the Small Explorer program to investigate the physical conditions of the solar limb, particularly the chromosphere of the Sun. The spacecraft consists of a satellite bus and spectrometer built by the Lockheed Martin Solar and Astrophysics Laboratory (LMSAL), and a telescope provided by the Smithsonian Astrophysical Observatory. IRIS is operated by LMSAL and NASA’s Ames Research Center.
The satellite’s instrument is a high-frame-rate ultraviolet imaging spectrometer, providing one image per second at 0.3 arcsecond angular resolution and sub-ångström spectral resolution.
NASA announced on 19 June 2009 that IRIS was selected from six Small Explorer mission candidates for further study, along with the Gravity and Extreme Magnetism (GEMS) space observatory.
The spacecraft arrived at Vandenberg Air Force Base, California, on 16 April 2013 and was successfully launched on 27 June 2013 by a Pegasus-XL rocket.
