descendant, Eleanora Atherton, in 1870. The books were originally uncatalogued and placed in the presses in size order. The first catalogue wasn't produced until 1791, and then was written in Latin and only listed the size and subject of each book. The practice of chaining the books was abandoned in the mid eighteenth century when gates were erected to prevent theft. Chetham's was the meeting place of Karl Marx and Friedrich Engels when Marx visited Manchester in the summer of 1845. Facsimiles of the economics books they studied can be seen on a table in the window alcove where they would meet. The research they undertook during this series of visits to the library led ultimately to their work, The Communist Manifesto. Therefore, the library acts as a site of historical importance for visiting communists. Additions were made to the buildings by J. E. Gregan (1850s), Alfred Waterhouse (1878) (grade II listed), and J. Medland Taylor (1883–95). Manchester Grammar School was extended along Long Millgate in 1870. Manchester Grammar School moved to Fallowfield in the 1930s, and after standing empty for many years the original building was destroyed during the Second World War, leaving only its new block. This became part of Chetham's School of Music in 1978. The old college building, which became the music school in 1969, still incorporates Chetham's Library and is Grade I listed. Librarians Past librarians include Robert Thyer (1709–1781), who became Librarian in 1732. Peter Hordern (died 1836) was librarian and also the minister of St Clement's Chapel, Chorlton. Thomas Jones held the position from 1845 to 1875; during his time, the size of the library more than doubled (from 19,000 volumes to 40,000 volumes). He also produced a two-volume catalogue of the library's collection in 1862 and 1863.
