Introduction

Harrison G. Dyer was an entomologist who named roughly 3,000 species of insects and 6,000 types of Lepidopterans by the end of his career. He dug a series of underground tunnels beneath two homes that he owned in Washington, D.C., creating multiple levels with stairs and electrical lighting throughout. A truck happened to be driving by one of his homes in 1924 when the driver felt one of his tires sinking. The hole had opened up in the street, revealing the tunnel below. Harrison confessed a few days later to having dug the tunnels in his spare time.
