Leif Erikson
Research done in the early 1960s by Norwegian explorer Helge Ingstad and his wife, archaeologist Anne Stine Ingstad, identified a Norse site located at the northern tip of Newfoundland. It has been suggested that this site, known as L'Anse aux Meadows, is "Leifsbúðir". The Ingstads demonstrated that Norsemen had reached America about 500 years before Christopher Columbus. Later archaeological evidence suggests that "Vinland" may have been the areas around the Gulf of St. Lawrence and that the L'Anse aux Meadows site was a ship repair station and waypoint for voyages there. That does not necessarily contradict the identification of L'Anse aux Meadows with "Leifsbúðir" since the two sagas appear to describe "Vinland" as a wider region which included several settlements. The "Saga of Erik the Red" mentions two other settlements in "Vinland": a settlement called "Straumfjǫrðr", which lay beyond "Kjalarnes" promontory and the Wonderstrands, and one called "Hóp", which was located even farther south.
Leif was described as a wise, considerate, and strong man of striking appearance. During his stay in the Hebrides, he fell in love with a noblewoman, Thorgunna, who gave birth to their son Thorgils. Thorgils was later sent to Leif in Greenland, but he did not become popular.
Alexander von Humboldt
Simón Bolívar wrote that "The real discoverer of South America was Humboldt, since his work was more useful for our people than the work of all conquerors." Charles Darwin expressed his debt to Humboldt, and admiration for his work, writing to Joseph Dalton Hooker that Humboldt was the ""greatest scientific traveller who ever lived"". Wilhelm von Humboldt wrote that "Alexander is destined to combine ideas and follow chains of thoughts which would otherwise have remained unknown for ages. His depth, his sharp mind and his incredible speed are a rare combination." Johann Wolfgang Goethe observed that "Humboldt showers us with true treasures." Friedrich Schiller wrote that "Alexander impresses many, particularly when compared to his brother - because he shows off more!" José de la Luz y Caballero wrote that "Columbus gave Europe a New World; Humboldt made it known in its physical, material, intellectual, and moral aspects." Napoléon Bonaparte remarked "You have been studying Botanics? Just like my wife!" Claude Louis Berthollet said "This man is as knowledgeable as a whole academy." Thomas Jefferson remarked "I consider him the most important scientist whom I have met." Emil Du Bois-Reymond wrote that "Every scientist is a descendant of Humboldt. We are all his family." Robert G. Ingersoll wrote that "He was to science what Shakespeare was to the drama."
