The Sins of the Children, also known as Father's Day and The Richest Man in the World, is a 1930 American pre-Code drama film, which was produced and directed by Sam Wood and distributed by Metro-Goldwyn-Mayer.
Adolf Wagenkampf, a German immigrant barber on the verge of becoming rich, takes his sickly son away on a two-year stay in a drier climate. The man's partner deems him a failure, but he learns that his family is more important than finance.
Elliott Nugent and his father were commissioned to write the script after the success of Wise Girls.
