Named in honor of Princess Stephanie of Belgium who in the year of discovery married Archduke Rudolf (1858–1889), Crown Prince of Austria and only son of Emperor Franz Joseph I (1830–1916). Rudolf’s later romance with a court beauty, Baroness Maria Vetsera, led to one of the most discussed tragedies of the day when they were found dead in his hunting lodge at Mayerling, near Vienna.
