Nov. 23, 1849 — Dr. George Parkman disappears at the Medical School in one of the most famous murder cases in Harvard history. Earlier, Parkman has lent money to colleague Dr. John White Webster. To secure the loan, Webster gives Parkman a mortgage on his personal property, including a valuable collection of minerals. When Parkman learns that Webster has backed another loan with the same collection, he begins relentlessly pursuing Webster to collect the debt.
A week after the disappearance, a suspicious janitor breaks through a brick vault below Webster’s lab and finds human body parts, which the authorities soon discover all around the lab. Found guilty of first-degree murder, Webster belatedly confesses and appeals for clemency, but is hanged on Aug. 30, 1850. Parkman’s widow leads a fund drive to support Webster’s wife and children.
