Joseph Earnshaw and his brothers, Henry and John, played an integral part in the early surveys performed in Cincinnati. Their surveys became significant when the field notes and most of the plats of Symmes original surveys were lost in a fire at Symmes house in 1810. With these documents destroyed, the Gest and Earnshaw surveys of the city were left as the earliest surviving survey records of Cincinnati.Music HallCincinnatis Music Hall was designed by Samuel Hannaford and completed in 1878. The property was first part of the citys largest burial grounds, Washington Cemetery. After its burials were relocated, many to Spring Grove Cemetery, the Cincinnati Childrens Asylum was built there. Joseph Earnshaws engineering firm surveyed the property in 1869, in preparation for the construction of the Sangerfest Hall, an exposition and entertainment hall. Within five years, the wood-framed exhibition hall had outgrown its usefulness, funds were raised, and Music Hall was built. During its rich history, it was home to political conventions and expositions, including the 1888 Centennial Exposition celebrating 100 years of Ohio Valley industry and agriculture. Today, it is home to a number of the citys cultural institutions, including the Cincinnati Symphony Orchestra, May Festival, Summer Opera, and the Cincinnati Ballet. Music Hall has earned a place on the National Register of Historic Places, listed as a National Landmark.Music Hall was also the site of a historic public meeting held on March 24, 1884. After a guilty verdict in a case where two men, Joseph Palmer and William Berner, murdered their employer, the citizens of the city gathered to discuss the state of criminal activity of Cincinnati. The meeting was peaceful until someone shouted To the jail! Come on! Follow me and hang Berner! Days of rioting ensued, ending in the burning of the courthouse, destroying decades of priceless court records.24
