L awn Park C onc eptThe success of the lawn park concept of cemetery design, utilized in Spring Grove Cemetery, led to consulting work on cemeteries in other cities. Adolf Strauch and Joseph Earnshaw provided advice, and even plans, free of charge, to Oakwoods Cemetery near Chicago (1864), Forest Lawn Cemetery in Buffalo (1866), and Woodmere Cemetery in Detroit (1869). Strauch also advised a one-time associate, Jacob Weidenmann, in the design of Cedar Hill Cemetery in Hartford, Connecticut. Strauch was a lifelong learner, and kept up an extensive correspondence with landscape gardeners in the U.S. and abroad. In 1863, the board of Spring Grove sent him on a three-month paid trip to Europe, in which he visited parks, zoos, and cemeteries, bettering many designs along the way. The influence of Strauch and his partnership with Earnshaws surveying and landscaping company can literally be seen around the world.approved by 23 of the 41 cemetery board members. The name was officially adopted twenty days later and a corporation of the Proprietors was established the following year, on January 28, 1845. 84Howard Daniels, the cemetery architect hired to design the cemetery grounds told the board he wished to have the laying out of the cemetery grounds and the survey of the same to be completed this season. 85The board commissioned Thomas Earnshaw to perform this initial survey on July 21, 1847. In 1850, Earnshaw, with the assistance of his sons, completed the survey, a job that took longer than the board anticipated. 86The surveying method the Earnshaw family used was based upon the principles of plane trigonometry, where the entire grounds were laid out in equilateral triangles having each side measuring exactly 200 feet.87This method of survey allows for the exact position of every lot, but prevents the avenues from ever being altered after the survey is completed, consequently no lot can ever be infringed upon and no error can arise to affect any other lot.88Right: Historic map of Spring Grove Cemetery, 187632
