"Dr. Heidegger's Experiment" is a short story by American author Nathaniel Hawthorne. The story is about a doctor who claims to have been sent water from the Fountain of Youth. Originally published anonymously in 1837, it was later published in Hawthorne's collection Twice-Told Tales, also in 1837. Plot Dr. Heidegger, an eccentric aged scientist, invites four elderly friends (Mr. Medbourne, a destitute man, who was a merchant in his youth but had squandered his wealth in wrong investments; Colonel Kiligrew, a elderly ailing man who had indulged himself in ‘sinful pleasures’; Mr. Gascoigne, a forgotten politician who displayed hypocrisy throughout his career; and the Widow Wycherley, a once-beautiful woman ostracised by her community for having a number of scandalous relationships, including with the three) to participate in an experiment in his mysterious, gloomy study. He shows them a withered rose that he claims is fifty-five years old, from his deceased fiancé Sylvia Ward (prior to their wedding, Sylvia had contracted a slight disorder; Heidegger had given her one of her experimental prescriptions, which killed her on her bridal evening). He then displays a vase, a gift from an acquaintance, that contains a generous quantity of sparkling water. Heidegger explains that this bewitching water is from the legendary Fountain of Youth, near Lake Macaco (now known as Lake Okeechobee, in Florida). The water wondrously causes the old rose to bloom again when it is dropped into it. Dr. Heidegger's friends become cautiously intrigued. They wish to taste the water, hoping it will restore their youth and give them an opportunity to live life again, free from the mistakes they made when they were young. As Heidegger watches, they anxiously drink the water. Their youth restored, they begin acting as fatuously as they did in their prime. Soon, the three men of the group begin competing for the attention of the now-youthful and beautiful widow. While experiencing their newfound youth, however, a tall ominous mirror in the study reflects an image of the four guests as still being elderly and feeble. The vase is accidentally smashed as the men fight over the widow, and its miraculous water is lost. As Heidegger protests against the four, the rose begins fading, restored back to its ‘dry and fragile’ state. To the four guests’ horror, they return to their old self. Heidegger realises that giving the four a second chance to live their youth once
