Ellis Island
Between 1905 and 1914, an average of one million immigrants per year arrived in the United States. Immigration officials reviewed about 5,000 immigrants per day during peak times at Ellis Island. Two-thirds of those individuals emigrated from eastern, southern and central Europe. The peak year for immigration at Ellis Island was 1907, with 1,004,756 immigrants processed. The all-time daily high occurred on April 17, 1907, when 11,747 immigrants arrived. After the Immigration Act of 1924 was passed, which greatly restricted immigration and allowed processing at overseas embassies, the only immigrants to pass through the station were those who had problems with their immigration paperwork, displaced persons, and war refugees. Today, over 100 million Americans—about one-third to 40% of the population of the United States—can trace their ancestry to immigrants who arrived in America at Ellis Island before dispersing to points all over the country.
Emory Ellis
Ellis was born on 29 October 1906 in Grayville, Illinois. He attended California Institute of Technology from 1925, attaining his PhD in 1934 in biochemistry. Apart from one year working for the Food and Drug Administration, Ellis remained at Caltech until World War II. Ellis' interests were in bacteriophage which he believed would contribute to understanding the role of viruses in cancer. He started work on their role in animals, but found that there were extra problems and expense related to maintaining the animals and so switched to phage. Ellis published the important paper "The Growth of Bacteriophage" with Max Delbrück in 1939. He gave up work on phage after this paper and returned to cancer research before moving to Naval Air Weapons Station China Lake from 1943, working with rocket-program employees as the onsite representative of Caltech. Ellis became Executive Director of the Office of Industrial Associates in Caltech for two years between 1963 and 1965 and retired in 1969. Ellis died on 26 October 2003.
