"

In 1924, Schweitzer returned to Africa without his wife, but with an Oxford undergraduate, Noel Gillespie, as his assistant. Everything was heavily decayed, and building and doctoring progressed together for months. He now had salvarsan for treating syphilitic ulcers and framboesia. Additional medical staff, nurse (Miss) Kottmann and Dr. Victor Nessmann,[11] joined him in 1924, and Dr. Mark Lauterberg in 1925; the growing hospital was staffed by native orderlies. Later Dr. Trensz replaced Nessmann, and Martha Lauterberg and Hans Muggenstorm joined them. Joseph also returned. In 1925–6, new hospital buildings were constructed, and also a ward for white patients, so that the site became like a village. The onset of famine and a dysentery epidemic created fresh problems.[citation needed]
