Question: Jonas Edward Salk (; October 28, 1914 - June 23, 1995) was an American medical researcher and virologist. He discovered and developed one of the first successful polio vaccines. Born in New York City, he attended New York University School of Medicine, later choosing to do medical research instead of becoming a practicing physician. In 1939, after earning his medical degree, Salk began an internship as a physician scientist at Mount Sinai Hospital.

In 1947, Salk became ambitious for his own lab and was granted one at the University of Pittsburgh, but the lab was smaller than he had hoped and he found the rules imposed by the university restrictive. In 1948, Harry Weaver, the director of research at the National Foundation for Infantile Paralysis, contacted Salk. He asked Salk to find out if there were more types of polio than the three then known, offering additional space, equipment and researchers. For the first year he gathered supplies and researchers including Julius Youngner, Byron Bennett, L. James Lewis, and secretary Lorraine Friedman joined Salk's team, as well. As time went on, Salk began securing grants from the Mellon family and was able to build a working virology laboratory. He later joined the National Foundation for Infantile Paralysis's polio project established by President Franklin D. Roosevelt. Extensive publicity and fear of polio led to much increased funding, $67 million by 1955, but research continued on dangerous live vaccines. Salk decided to use the safer 'killed' virus, instead of weakened forms of strains of polio viruses like the ones used contemporarily by Albert Sabin, who was developing an oral vaccine. After successful tests on laboratory animals, on July 2, 1952, assisted by the staff at the D.T. Watson Home for Crippled Children, Salk injected 43 children with his killed-virus vaccine. A few weeks later, Salk injected children at the Polk State School for the retarded and feeble-minded. In 1954 he tested the vaccine on about one million children, known as the polio pioneers. The vaccine was announced as safe on April 12, 1955. The project became large, involving 100 million contributors to the March of Dimes, and 7 million volunteers. The foundation allowed itself to go into debt to finance the final research required to develop the Salk vaccine. Salk worked incessantly for two and a half years. Salk's inactivated polio vaccine was the first vaccine for the disease; it came into use in 1955. It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system.

Question: Seward was born in on May 16, 1801, in the small community of Florida, New York, in Orange County. He was the fourth son of Samuel Sweezy Seward and his wife Mary (Jennings) Seward. Samuel Seward was a wealthy landowner and slaveholder in New York State; slavery was not fully abolished in the state until 1827. Florida was located some 60 miles (97 km) north of New York City, west of the Hudson River, and was a small rural village of perhaps a dozen homes.

Despite his public nonchalance, Seward was devastated by his convention loss, as were many of his supporters. The New Yorker was the best-known and most popular Republican, and his defeat shocked many in the North, who felt that Lincoln had been nominated through chicanery. Although Seward sent a letter stating Weed was not to blame, Seward's political manager took the defeat hard. Seward was initially inclined to retire from public life, but received many letters from supporters: distrustful of Lincoln, they urged Seward to remain involved in politics. On his way to Washington to return to Senate duties, he stopped in Albany to confer with Weed, who had gone to Lincoln's home in Springfield, Illinois to meet with the candidate, and had been very impressed at Lincoln's political understanding. At the Capitol, Seward received sympathy even from sectional foes such as Jefferson Davis. Lincoln faced three major opponents. A split in the Democratic Party had led northerners to nominate Senator Douglas, while southerners chose Vice President John C. Breckinridge. The Constitutional Union Party, a new party consisting mostly of former Southern Whigs, selected former Tennessee senator John Bell. As Lincoln would not even be on the ballot in ten southern states, he needed to win almost every northern state to take the presidency. Douglas was said to be strong in Illinois and Indiana, and if he took those, the election might be thrown into the House of Representatives. Seward was urged to undertake a campaign tour of the Midwest in support of Lincoln and did so for five weeks in September and October, attracting huge crowds. He journeyed by rail and boat as far north as Saint Paul, Minnesota, into the border state of Missouri at St. Louis, and even to Kansas Territory, though it had no electoral votes to cast in the election. When the train passed through Springfield, Seward and Lincoln were introduced, with Lincoln appearing "embarrassed" and Seward "constrained". In his oratory, Seward spoke of the U.S. as a "tower of freedom", a Union that might even include Canada, Latin America, and Russian America. New York was key to the election; a Lincoln loss there would deadlock the Electoral College. Soon after his return from his Midwest tour, Seward embarked on another, speaking to large crowds across the state of New York. At Weed's urging he went to New York City and gave a patriotic speech before a large crowd on November 3, only three days before the election. On Election Day, Lincoln carried most Northern states, while Breckinridge took the Deep South, Bell three border states, and Douglas won Missouri--the only state Seward campaigned in that Lincoln did not win. Lincoln was elected.
