Sydney T. (Sydney Turner) Klein

Sydney Turner Klein was a British writer born in 1853 and died in 1934. Reliable library and archival sources confirm him as the author of Science and the Infinite; or, Through a Window in the Blank Wall, and also connect him with other spiritual and philosophical works including From the Watch Tower and The Way of Attainment.

Biographical material from specialist historical sources shows that he came from the Klein family of the London import-export firm William Klein and Sons, attended Haileybury, and later became a partner in the family business before retiring because of ill health. He was also a Fellow of the Royal Astronomical Society, a detail that helps explain the scientific cast of some of his writing.

His books are remembered for trying to reconcile scientific curiosity with religious and metaphysical reflection. Rather than writing in a narrowly academic way, he aimed at general readers and invited them to think about the visible world as a clue to larger unseen realities.
