Headline and accompanying photograph printed in the November 6, 1924 edition (page 10) of the St. Paul Daily News. The story that follows described the vaccination of hundreds of children and adults against smallpox. The vaccinations were carried out in the basement of the St. Paul courthouse. The photograph shows deputy health commissioner Dr. Nichols (first name not specified) vaccinating patient Donald Hirsch as his sister, Sylvia Hirsch, looks on.

Minnesota's worst known encounter with smallpox came in 1924 and 1925. Five hundred people died—four hundred of them in the Twin Cities. Almost 90 percent of the Twin Cities deaths took place in Minneapolis.

Around the world and over the centuries, smallpox has killed millions. Early European explorers and conquerors brought it to the Americas. Some historians believe it killed up to 95 percent of the native people of what is now the United States. Whether it reached Minnesota before European settlement began is not known.

Smallpox comes in two varieties, one mild and one deadly (also called black, or virulent, or hemorrhagic.) In the late 1800s and early 1900s, the mild type was common in Minnesota and killed few people. The deadly type appeared in scattered outbreaks, also killing relatively few. The worst period had been 1871–1872, when 273 people died, but since then the average had fallen to less than fifteen deaths a year. People did not much fear it.

The first 1924 deaths took place in Duluth in January and were followed by more in Minneapolis in the last week of June. They raised little alarm. A few more people died over the summer. In the fall, when people began to huddle indoors, the disease spread: twenty-seven died in October, sixty-six in November, and 149 in December.

At the time, about 240,000 people lived in St. Paul and 410,000 in Minneapolis. Had the disease affected both cities' populations equally, there would have been ninety-one deaths in St. Paul and 129 in Minneapolis. But at the end of 1924, 208 people had died in Minneapolis and only twelve in St. Paul.

Two factors explain the difference. First, Minneapolis had a higher population density. St. Paul and Minneapolis were about the same size in area, but Minneapolis fit 170,000 more people into an equivalent space. It had more flophouses, shelters, and boardinghouses, all of which pressed sometimes sickly people into close quarters. In these conditions, the airborne smallpox virus spread quickly.

Second, St. Paul's public health system responded more efficiently to the crisis. Its workers were better trained, and they acted more quickly to quarantine victims and trace the sources of infection. Minneapolis public health officers, perhaps overwhelmed by the scope of their problem, acted less efficiently in training hospital workers, tracing sources of the virus, and warning schools, businesses, and families of danger when infection appeared. They also put smallpox victims in the public hospital, infecting new victims. St. Paul officials isolated as many of the ill as they could in a "pest house" far from the center of town.

State law blocked a sound public health response. An 1883 state law had required all school-age children to be vaccinated against smallpox. But in 1903, the legislature repealed that law and made compulsory child vaccination illegal. Although smallpox vaccination is almost 100 percent effective, public health officers had no power to make people protect themselves. They could recommend, but not mandate, the vaccine.

Starting in November 1924, both cities launched free vaccination campaigns. Once the deaths mounted, the frightened public jammed the vaccination centers. As reported in the Minneapolis Journal, as many as 17,000 got their skin scratches in a single day. By mid-December 1924—according to public health officials—some 210,000 people in St. Paul and 350,000 in Minneapolis had been vaccinated.

December was the worst month; 129 people died in Minneapolis alone. But by then the tide had turned. The disease had carried off the most vulnerable before mass vaccination took effect. Eighty-eight people died in January 1925 and thirty in February (all in Minneapolis). By late summer, the epidemic had passed.

The final toll of suffering was grim. St. Paul reported 855 smallpox cases and thirty-eight deaths, suggesting a 4.4 percent death rate. Minneapolis reported 1430 cases and 365 deaths, indicating a death rate almost six times as high (25.5 percent). Another 101 people died around the state. Though occasional deaths took place into the early 1940s, smallpox as an epidemic never returned.

Turning Point

The epidemic peaks in December 1924 with 149 smallpox deaths in Minneapolis and St. Paul. But the vaccination total also reaches its peak at 460,000 people in the two cities combined. The death rate falls sharply in January and February.

Chronology

c.1500

Smallpox and other diseases are introduced to North America. Over the next three hundred years, they kill roughly 95 percent of the continent's native population.

1796

Dr. Edward Jenner devises a new method of smallpox inoculation, improving on a practice in use around the world for more than two thousand years.

1871–1872

More than 270 Minnesotans die from smallpox, mostly in lumber camps. It stands as the worst smallpox epidemic in state history until the outbreak of 1924–1925.

1881–1882

Ninety-six people die during Minnesota's then-second-worst smallpox season.

1883

The Minnesota legislature requires parents to vaccinate their children against smallpox, but provides neither money for vaccines nor enforcement measures.

1903

The Minnesota legislature repeals the 1883 vaccination statute and declares forced vaccination of school-age children illegal.

1923

The yearly smallpox death rate is comparatively low. Since 1899, it has ranged from one to fifty-five people, with an average of sixteen.

January, 1924

The first death of the Minnesota epidemic occurs in Duluth.

December 4, 1924

Despite one hundred recent deaths, Minneapolis declares itself "the safest city" in the country from smallpox. Another 260 people would die in the city in the next nine months.

1925

The last death from the epidemic occurs in August.

1941

The last recorded smallpox victim dies in Minnesota.









  

Comments

I am curious if I can find out when in August the last death occurred. My great-grandfather, who lived in St. Paul, died August 23, 1925 of smallpox.

Hi Christine, thanks for your comment and interest in MNopedia. Could you provide us with your great-grandfather's name? We could then check his name against official state reports of the outbreak that are held here at the Minnesota Historical Society.

Thanks,
Peter DeCarlo, Editorial Assistant, MNopedia

Christine,
The state department of health published what it believed was a complete list of the smallpox victims of 1924 and 1925. I found that list at MHS and have a copy in front of me. It recorded only one death in August of 1925, an infant named Marie Pablicek. It may be that public health officers missed your grandfather's case.
