Oh, it's worth mentioning that another movement derived from theosophy, ariosophy, went on to form the basis of Nazi cosmology.
All of these movements originated in turn of the century Europe and largely reflect the values of the era. And all of them, particularly the anthroposophists, are extremely aggressive about reputation management and sanitizing their histories.
Ah, and one final point -- the founders of the organic food movement were students of Rudolf Steiner, the originator of anthroposophy, who popularized his own system of agriculture -- biodynamics. A lot of cultural norms and attitudes in modern alternative health and natural food circles began with anthroposophy, and theosophy, by extension -- including the anti-vaccination movement. Weleda, a natural skincare company founded by Steiner still operates today.
