a tall ridge running along 1st Street. Between 1890 and 1910, well-to-do families built mansions on the North Side. Only a few are genuine mansions; the wealthiest Germans lived on the East and West Sides. Some are picturesque Queen Annes, with corner turrets and rambling floor plans. In 1984, the First Street corridor became an official historic district, listed on the National Register of Historic Places. This area was first settled by German immigrants in the 19th century and served as a key German-American business community for Milwaukee. Daniel Richards, who started Milwaukee's first newspaper, bought a home in 1842 at 2863 N. 1st Street on 160 acres (65 ha) of land that ran from Richards Street west to between 5th and 6th and from Center Street north to Burleigh Street. The home stood until 2002. Richards Hill is located immediately north of Hadley Street between 2nd Street and Palmer, and is the location of the highest natural point in the city. Richards Hill contains thousands of perennials planted by Daniel Richards 160 years ago. The city limits expanded to the north, reaching Center Street in 1855 and Burleigh a year later. In the 1870s, however, city residents crossed North Avenue and began to develop the former farming district. By 1900, the tide of settlement had reached near Burleigh Street. First, Second and Palmer streets (between North Avenue and Center Street) became the major "gold coast" of the North Side German community. The streets were lined with the homes of merchants, manufacturers, and professionals. Perhaps the best known was Edward Schuster, founder of what was, for decades, Milwaukee's largest department store chain. Wealthy residents organized the Millioki Club and built a lavish clubhouse at First and Wright streets. As the neighborhood filled in, its northeastern corner was developed as a large-scale industrial district. The neighborhood remained heavily ethnic German through the 1920s, but there were signs of demographic change. Many of the new residents in the northern sections were ethnic Polish and Italian families, immigrants and their descendants who had moved across Holton Street from the Riverwest neighborhood. In the southern sections, scores of German families moved on to new neighborhoods, and the blocks above North Avenue provided homes for a variety of groups, among them African Americans. The first Black families arrived in the 1930s, during the Great Migration from the South. They moved up the Third Street corridor,
