In 1906, in the year that Leonard L Kolkman was born, English biochemist Frederick Hopkins concluded that vitamins are essential to the human body and that a lack of vitamins caused scurvy and rickets. Scurvy and rickets were both huge problems in sailors that were at sea for extended time and the addition of vitamin C, vitamin D, and calcium in their diets helped eradicate the problem.

In 1914, by the time he was just 8 years old, in August, the Panama Canal opened to traffic. Begun by the French in the 1880's and abandoned, the United States undertook further construction in 1904. After 10 years, and the elimination of malaria carrying mosquitoes (which caused immense delays for the French and the Americans), the 48 mile long artificial waterway - a series of locks - created a shortcut for ships traveling between the Atlantic and Pacific Oceans.
