Personal life
In 1908 Oscar and Johanna married and resettled in Milwaukee. The Werwaths had four children; Karl (1909-1979), Greta (1910-2003), Hannah (1913-1984), and Heinz (1916-1987), all of whom worked at the Milwaukee School of Engineering at some point in their life. Karl, Oscar's oldest son, was a graduate of his father's school in 1936 and became president one month after his father's death in 1948 until 1977. ==References==
