The sphere, cylinder and cube of Froebel's second gift are the basis for this design by Wilhelm Middendorf. Created in 1852 by Ernst Luther a descendant of the family Martin Luther. In 1817, the three hundredth anniversary of the Reformation, Froebel became concerned that two of the descendants of Martin Luther were living in poverty. He undertook the education of Ernst and his brother at Keilhau

Some years later a new gravestone was donated, which incorporated Middendorf's design.
