Context: Alfred Stillé (October 30, 1813 – September 24, 1900) was an American physician.  Born in Philadelphia, he studied classics at Yale, but was expelled for participating in the Conic Sections Rebellion.  He then transferred to the University of Pennsylvania in the same year, where he received an A.B. degree in 1832.  He went on to get an A.M. from the University of Pennsylvania in 1835 and in 1836 an M.D. from the school's department of medicine.  He settled to practice in his native city, but spent parts of 1841 and 1851 in Paris and Vienna.  From 1854 to 1859 he was professor of medicine at the Pennsylvania Medical College and from 1864 to 1884 at the University of Pennsylvania, later becoming its Chair.  Stillé was one of the first in America to distinguish between typhus and typhoid fever.  His observations in this connection he made during a typhus epidemic in Philadelphia in 1836 and reported in 1838.  He acquired a great reputation as a practitioner, teacher, and writer, and was the first secretary, and in 1871–72 the president, of the American Medical Association.  However, as evidenced by his later writings, he was also known for refusing to accept the germ theory or laboratory medicine. Paul Whelton is an American physician scientist who made seminal contributions to hypertension and kidney disease epidemiology.  He also mentored numerous public health leaders including the Deans of the schools of public health at Johns Hopkins (Michael Klag) and Columbia (Linda Fried).  He currently serves as the Chwan Health System Endowed Chair in Global Public Health and a Clinical Professor in the Department of Epidemiology at the Tulane University School of Public Health and Tropical Medicine.  He is the founding director of the Welch Center for Prevention, Epidemiology, and Clinical Research at the Johns Hopkins University in Baltimore, Maryland. Mary Lucy Dosh (September 15, 1839 – December 29, 1861) was a Catholic nun in the order of the Sisters of Nazareth.  She was a volunteer nurse in Western Kentucky during the American Civil War, caring for both Union troops and Confederate prisoners of war, and died in the course of duty from typhoid fever.  In 2012, the United States Congress passed a resolution honoring Dosh's nursing care given to both Union and Confederate soldiers. Rear Admiral Susan Blumenthal, M.D. (born 1951) is an American physician, global health expert, psychiatrist and public health advocate.  With more than two decades of service as a senior government health leader in the administrations of four U.S. presidents, Rear Admiral Blumenthal served as the first Deputy Assistant Secretary for Women’s Health and Director of the Office on Women’s Health within the U.S. Department of Health and Human Services (HHS), as well as Assistant Surgeon General of the United States and Senior Global Health Advisor within the HHS.  She also was a Research Branch Chief at the National Institutes of Health (NIH), and the Chair of the NIH Health and Behavior Coordinating Committee.

The Public Health Advisor, or “PHA” is a type of public health worker which was established in 1948 by the United States Public Health Service in the Venereal Disease Control Division.  Today they are hired primarily by the U.S. Centers for Disease Control and Prevention (CDC) and serve in many public health programs.  This type of worker is unique in public health, because they begin their service at the entry level of public health doing what is known as “field work” or “contact epidemiology” which refers to the interviewing and locating of people who have been exposed to an infectious disease so as to offer them treatment and to reduce the epidemic.  Following their initial work experiences, PHAs are exposed to a variety of public health programs across the United States, learning to function at all levels of the public health system.  During their time of service, PHAs are called upon to respond to public health or humanitarian crisis.  This article will briefly describe the history of the Public Health Advisor and will mention a few notable contributions made over the course of their history with the Public Health Service and later with the Centers for Disease Control and Prevention. Sara Josephine Baker (November 15, 1873 – February 22, 1945) was an American physician notable for making contributions to public health, especially in the immigrant communities of New York City.  Her fight against the damage that widespread urban poverty and ignorance caused to children, especially newborns, is perhaps her most lasting legacy.  In 1917, she noted that babies born in the United States faced a higher mortality rate than soldiers fighting in World War I, drawing a great deal of attention to her cause.  She also is known for (twice) tracking down Mary Mallon, the infamous index case known as Typhoid Mary. Steven Kenneth Galson (born 1956) is an American public health physician.  He is currently Senior Vice President for Global Regulatory Affairs at Amgen, the S. California-based innovative global biopharmaceutical company.  He is also Professor-at-Large at the Keck Graduate Institute for Applied Life Sciences in Clarmont, California.  He is a retired rear admiral in the United States Public Health Service Commissioned Corps and public health administrator who served as the acting Surgeon General of the United States from October 1, 2007 – October 1, 2009.  He served concurrently as acting Assistant Secretary for Health from January 22, 2009 to June 25, 2009, and as the Deputy Director and Director of the Center for Drug Evaluation and Research (CDER) at the Food and Drug Administration from 2001 to 2007.  As the Acting Surgeon General, he was the commander of the United States Public Health Service Commissioned Corps and, while serving as the Assistant Secretary for Health, was the operational head of the Public Health Service. Cherokee Bluffs is an unincorporated community in Tallapoosa County, Alabama, United States.  The bluffs were a landmark in Tallapoosa County, and they were chosen as the first site on the Tallapoosa River for the creation of a dam and reservoir.  Martin Dam was built at Cherokee Bluffs and completed in 1939.  During construction, the community had bathouses, bunkhouses, a school, commissary, dining hall, recreation hall, camp hospital, and a barber shop.  The workers were tested for typhoid fever and malaria, and were not hired if they tested positive for malaria.  Local residents were also tested for malaria.  Cherokee Bluffs is the birthplace of Roy C. Craven, the founding director of the University Gallery at the University of Florida. Ephraim Saul "Andy" Anderson, CBE, FRS (28 October 1911 – 14 March 2006) was a British bacteriologist, best known for his work highlighting the human health dangers of drug-resistant bacteria created by antibiotics, in particular by low-dose antibiotic use in animal feeding.  Anderson was born of Estonian-Jewish immigrants in a working-class area of Newcastle upon Tyne, and educated at Rutherford College before winning a scholarship to attend Durham University's Medical School.  .  He served in the Royal Army Medical Corps during the Second World War.  Anderson won worldwide recognition for his work on the plasmids that render the bacteria responsible for typhoid fever and bacterial food poisoning insensitive to antibiotics.  Anderson was director of the Enteric Reference Laboratory of the Public Health Laboratory Service, between 1954-1978.  He was made a fellow of the Royal Society in 1968 and appointed a CBE in 1976. Mary Mallon (September 23, 1869 – November 11, 1938), better known as Typhoid Mary, was the first person in the United States identified as an asymptomatic carrier of the pathogen associated with typhoid fever.  She was presumed to have infected 51 people, three of whom died, over the course of her career as a cook.  She was twice forcibly isolated by public health authorities and died after a total of nearly three decades in isolation.
