An experiment for determining the ability of canines to form a self-governing society. Basically, the experiment will involve a group of dogs trained to train other dogs to perform typically human run tasks. I've begun training my miniature schnauzer, Riley, to operate vault doors, which I think is a promising start to the experiment. I'd be happy to bring her in any time to demonstrate.”— Liam's senior "thesis" proposal
Liam Hornwright was the son of Daniel Hornwright, mining magnate and CEO of Hornwright Industrial Mining Company. A student of Vault-Tec University, Liam was, in the words of Dean Harland Elliot, attending school primarily to party and spends the majority of his time in a haze of marijuana. Doing less than the bare minimum and insulting the faculty staff with his proposal quoted above, he was nonetheless retained due to his family connections and the ire that expelling him would bring.
Liam Hornwright is only mentiond in Fallout 76.
