Passage: From 1922 until his death in 1950 Ramana lived in Sri Ramanasramam, the ashram that developed around his mother's tomb. Ramana often walked from Skandashram to his mother's tomb. In December 1922 he did not return to Skandashram, and settled at the base of the Hill, and Sri Ramanasramam started to develop. At first, there was only one hut at the samadhi, but in 1924 two huts, one opposite the samadhi and the other to the north, were erected. The so-called Old Hall was built in 1928. Ramana lived there until 1949.Sri Ramanasramam grew to include a library, hospital, post-office and many other facilities. Ramana displayed a natural talent for planning building projects. Annamalai Swami gave detailed accounts of this in his reminiscences. Until 1938, Annamalai Swami was entrusted with the task of supervising the projects, and received his instructions from Ramana directly.

Question: When did Ramana die?
