The eldest was Fanny Imlay (1794–1816), who committed suicide as a young woman. Charles Gaulis Clairmont ended up as Chair of English literature at Vienna University and taught sons of the royal family; news of his sudden death in 1849 distressed Maximilian. Mary Godwin (1797–1851) gained fame as Mary Shelley, author of "Frankenstein". Half a year younger than her was Claire Clairmont, Mary Jane's only daughter, to whom she showed favouritism. The youngest, and the only child of the second marriage, was William Godwin the Younger (1803–1832). Godwin sent him first to Charterhouse School and then to various other establishments of a practical bent. Nonetheless, he eventually earned his living by the pen. He died at 29, leaving the manuscript of a novel, which Godwin saw into print. All of Godwin's children who lived into adulthood worked as writers or educators, carrying on his legacy and that of his wives. Only two of them had children who in turn survived: Percy Florence Shelley, and the son and daughter of Charles. Godwin did not welcome the birth of Allegra Byron, but Claire's only child died aged five.
