Albert's swarm was an immense concentration of the Rocky Mountain locust that in 1875 swarmed the Western United States. It was named after Albert Child, a physician interested in meteorology, who calculated the size of the swarm to 198,000 square miles (510,000 km2) by multiplying the swarm's estimated speed with the time it took for it to move through southern Nebraska.[1]

The 1875 swarm is referred to repeatedly in a western Missouri historical record that explains:[2]

It was the year 1875 that will long be remembered by the people of at least four states, as the grasshopper year. The scourge struck Western Missouri April, 1875, and commenced devastating some of the fairest portions of our noble commonwealth. They gave Henry [County] an earnest and overwhelming visitation, and demonstrated with an amazing rapidity that their appetite was voracious, and that everything green belonged to them for their sustenance.

One estimate numbers the locusts in the swarm at 3.5 trillion.[3]
