At the age of 22, Jacob Lienau went to Neustadt as a young businessman and opened a grocery store. Soon he was able to expand and became a grain wholesaler. He bought six merchant ships and got so much wealth that he built a representative house with a park in Neustadt. In addition to his professional career, Jacob Lienau was socially and culturally committed. At his suggestion, a new church tower was built in 1846 as the town's landmark. Between 1844 and 1854 he was in command of the Neustädter Schützengilde. The painter Detlev Conrad Blunck portrayed Jacob Lienau and his family around 1850.
Because of his achievements and merits, Jacob Lienau was named Neustadt's first honorary citizen in 1878. His life's work for the city was also honored by naming a school in Neustadt after him.
