From the moment of his birth she had only one wish with regard to her child--to be rid of him. A long procession of lovers had left her wholly incapable of shame. But the child would be a worry--and she did not mean to be worried! If the father had better instincts--well, let him follow them. He did. He employed Molin, Madame de Tencin’s doctor, to find out the baby’s nurse, Anne Lemaire, and claim the little creature from her. The great d’Alembert told Madame Suard many years after how Destouches drove all round Paris with the baby (‘with a head no bigger than an apple’) in his arms, trying to find for him a suitable foster-mother. But little Jean Baptiste Lerond seemed to be dying, and no one would take him. At last, however, Destouches discovered, living in the Rue Michel-Lecomte, a poor glazier’s wife, whose motherly soul was touched by the infant’s piteous plight, and who took him to her love and care, and kept him there for fifty years. History has concerned itself much less with Madame Rousseau than with Madame de Tencin. Yet it was the glazier’s wife who was d’Alembert’s real mother after all. If she was low-born and ignorant, she had yet the happiest of all acquirements--she knew how to win love and to keep it. The great d’Alembert, universally acclaimed as one of the first intellects of Europe, had ever for this simple person, who defined a philosopher as ‘a fool who torments himself during his life that people may talk of him when he is dead,’ the tender reverence which true greatness, and only true greatness perhaps, can bear towards homely goodness. From her he learnt the blessing of peace and obscurity. From his association with her he learnt his noble idea--difficult in any age, but in that age of degrading luxury and self-indulgence well nigh impossible--that it is sinful to enjoy superfluities while other men want necessaries. His hidden life in the dark attic above her husband’s shop made it possible for him to do that life’s work. For nearly half a century he knew no other home. When he left her roof at last, in obedience to the voice of the most masterful of all human passions, he still retained for her the tenderest affection, and bestowed upon her and her grandchildren the kindness of one of the kindest hearts that ever beautified a great intelligence. Little Jean Baptiste was put to a school in the Faubourg Saint-Antoine, where he passed as Madame Rousseau’s son. General Destouches paid the expenses of this schooling, took a keen pleasure in the child’s brightness and precocity, and came often to see him. One day he persuaded Madame de Tencin to accompany him. The seven-year-old Jean Baptiste remembered that scene all his life. ‘Confess, Madame,’ says Destouches, when they had listened to the boy’s clever answers to his master’s questions, ‘that it was a pity to abandon such a child.’ Madame rose at once. ‘Let us go. I see it is going to be very uncomfortable for me here.’ She never came again.
