Some information taken from the Newfoundland and Labrador Heritage website.
The first Europeans known definitely to set foot in Newfoundland were the Norse. L'Anse aux Meadows, on Newfoundland’s northern peninsula appears to have been a small Norse settlement of about eight buildings and no more than 75 people, mostly sailors, carpenters, blacksmiths, hired hands and perhaps even serfs or slaves. It is probable therefore that the settlement was a base camp for repairing and maintaining Norse ships. Archaeologists have concluded that the habitation there was little more than a seasonal camp, never occupied for more than a few seasons, and never developing into the sort of permanent settlement which had been established in Greenland.
Placentia, known as "ye ancient capital," was founded by the French.
Italian-born Guglielmo Marconi began experimenting with wireless telegraphy in 1894. In December of 1901, Marconi assembled his receiver at Signal Hill, St. John's, nearly the closest point to Europe in North America. He set up his receiving apparatus in an abandoned hospital that straddled the cliff facing Europe on the top of Signal Hill. After unsuccessful attempts to keep an antenna aloft with balloons and kites, because of the high winds, he eventually managed to raise an antenna with a kite for a short period of time for each of a few days. On December 12th, Marconi pressed his ear to the telephone headset of his rudimentary receiver and successfully heard "pip, pip, pip" - 1700 miles from the transmitter. This demonstrated that transatlantic wireless communication was possible. In 1904, Marconi installed a wireless station at Cape Race, the station that was later to receive the SOS message from the Titanic in 1912.
Memorial University College (MUC) officially opened on 15 September 1925, and began to offer the first two years of university training in the arts and sciences. Today it is called the Memorial University of Newfoundland, and is the largest university in Atlantic Canada. Memorial has built and cultivated a number of large research
Pollux and the S.S. Truxton - to run aground near St. Lawrence within two
miles and a few hours of each other. When the alarm went out, men rushed from the Director and Iron Springs mines to the scene of the disaster. Some risked life and limb by launching dories into the storm toward the stricken vessels. Others threw ropes from cliff tops down to the beaches and hauled the sailors inch by inch up the precipice, using mine lamps to illuminate their work. Those survivors who could, walked back to town. The rest were pulled on sleds to the Iron Springs mine for first aid and then to St. Lawrence for soup and shelter. Altogether, 182 men were saved by the local people. When the American sailors returned home they praised their rescuers so highly that the United States government felt moved to present St. Lawrence with a hospital.
