Born on May 3, 1849, in Ribe, Denmark, Riis grew up in a large family. He was one of 15 children. His father was a schoolteacher and a writer for a local newspaper. Riis experienced personal tragedy when his brother Theodore drowned when Jacob was eleven. Even as a child, he showed a desire to help others. He once donated his money to a poor family in Ribe. This early empathy likely shaped his future career as a reformer.
In 1870, at age 21, Riis immigrated to the United States. He traveled from Copenhagen to New York City to work as a carpenter. 
During this era, American cities were changing very quickly. After the Civil War, millions of people moved into urban areas. In the 1880s, the Lower East Side of New York was the most densely populated place on earth. 
To capture these dark spaces, Riis used new technology. He was an early user of casual photography and photographic flash. This allowed him to take clear pictures in dark, crowded rooms. 
Beyond housing, Riis fought against the disease tuberculosis. He had lost six of his brothers to this illness. In 1906, he learned about Christmas seals in Denmark. These were special stamps used to raise money for health causes. Riis wrote an article called "Christmas stamps" to bring this idea to America.
