Born into a farming family in the unincorporated community of Deer River in
Lewis County, Swinburne lost his father at the age of twelve and had to work to support himself as well as assume responsibility for his mother and sisters. He sought summertime work on farms and, during wintertime, attended the county's public schools and academies in nearby towns of
Denmark and
Lowville, as well as
Fairfield in neighboring
Herkimer County. Graduating from
Albany Medical College, first in his 1846 class, he began a practice as physician and surgeon. In 1861, at the start of the Civil War, he was appointed by commander of
New York National Guard, Brigadier General
John F. Rathbone, to serve as chief medical officer at Albany depot. In June 1862, following
Battle of Savage's Station, as
Army of the Potomac, along with its physicians, retreated, Swinburne remained to care for the thousands of wounded prisoners, both
Union and
Confederate. Respecting his principled stand, Confederate commander
Stonewall Jackson gave him a pass, with an accompanying personal note, permitting visits to Union prisoners. In 1864, Governor
Horatio Seymour nominated him to the post of Health Officer of the Port of New York and, in 1867, he was renominated by Governor
Reuben Fenton, serving a total of six years, until 1870. During his administration, despite the state legislature's reluctance to assign funding, he supervised the construction of then-state-of-the-art quarantine facilities on islands which were named
Swinburne and
Hoffman. While on a trip to Europe in July 1870, following retirement from the port, he arrived in
France at the outbreak of the
Franco-Prussian War. In September, as the
Siege of Paris began, he was importuned by the city's American community to form, at their expense, the Parisian equivalent of the Civil War
U.S. Ambulance Corps. For the next six months, through the fall of Paris to the
Prussian Army on January 28, 1871, until his departure on March 18, the first day of the revolutionary
Paris Commune, the ambulance corps operated on a wide-ranging scale throughout the city, obtaining results beyond the over-stretched capacities of the local physicians. In recognition of his efforts, the newly formed
Third Republic awarded him the decoration of Chevalier [Knight] in
Legion of Honor, the country's highest distinction. He was also decorated by the
Red Cross of Geneva. ==As physician, mayor and congressman==
