In the late 1890s, Mandus intended to expand and update his factories with new machinery to make his product-lines more efficient and safer for his workers, but this decision had dire consequences. Mandus promised to her on her deathbed he would take care of them both she was buried in 1890, and her teeth sold to make dollies for the poor. She'd given birth to twin sons, Edwin and Enoch. Tragedy struck Mandus's family when Lily, his wife, died due to complications from childbirth, and Mandus grieved and mourned her loss ever since. He had a collection of rifles and a museum of stuffed and fully mounted skins of some large mammals on display, including a hippopotamus, a giant anteater, and a grizzly bear. Mandus was something of either a hobbyist or a hunter.
He later became the head of the family and happily married Lillibeth 'Lily' Mandus. Oswald Mandus was born into an English family who owned a massive meat processing factory, possibly the largest in London, that was established in 1828.
