Otto Karl Mullennex

On April 8, 2026, Otto Karl Mullennex died at home in Green Bay. He was 90. He was born on May 27, 1935 in a German-American family that measured love in finished chores. He learned early that a day is something you finish, not something you wait for. He issued valves that kept mills from improvising danger. A digester sample valve key by the locker stayed clean enough to trust. Colleagues still mention a digester sample valve key. He married Margaret in 1957. They kept a house that stayed modest when the neighborhood did not. They raised three sons through public schools and ordinary weather. After Margaret died in 2019, he kept the routines that still made sense: the walk, the garden, the Sunday call. Neighbors remember someone who swept the sidewalk past the property line when weather had been unfair. Mornings were his favorite shift at home. He died in Green Bay, on streets that already knew his pace. The chair by the window still holds the shape of a habit.
