The Volunteers of Camp Lazear

In November 1900, at a small experimental station outside Havana, Cuba, Private John Kissinger stood before Major Walter Reed and spoke words that stunned the room. He volunteered to be bitten by mosquitoes deliberately infected with yellow fever — a disease that killed roughly twenty percent of those it struck. When offered one hundred dollars in gold for his participation, Kissinger refused it. He was not doing this for money.

Kissinger was not the first to risk everything. Weeks earlier, Dr. Jesse Lazear, a member of Reed's Yellow Fever Commission, had allowed an infected mosquito to feed on his arm. Within days, the thirty-four-year-old physician developed a raging fever. On September 25, 1900, Lazear was dead — leaving behind a wife and two small children. Dr. James Carroll had also volunteered and nearly died, his heart permanently damaged by the disease.

Their sacrifice was not wasted. The experiments at Camp Lazear proved definitively that the Aedes aegypti mosquito transmitted yellow fever, a discovery that would save countless thousands of lives across the tropics for generations to come.

Jesus said, "Greater love has no one than this: to lay down one's life for one's friends." These men stretched that circle wider — they laid down their lives for strangers they would never meet, for children not yet born. That is the shape of sacrificial love. It does not calculate the cost. It sees the suffering of others and steps forward, arms outstretched, saying, "Take me instead."
