The ‘Taos Hum’ is a low-pitched sound heard in numerous places worldwide, especially in the USA, UK, and northern europe. It is usually heard only in quiet environments, and is often described as sounding like a distant diesel engine. Since it has proven indetectable by microphones or VLF antennae, its source and nature is still a mystery.

In 1997 Congress directed scientists and observers from some of the most prestigious research institutes in the nation to look into a strange low frequency noise heard by residents in and around the small town of Taos, New Mexico. For years those who had heard the noise, often described by them as a “hum”, had been looking for answers. To this day no one knows the cause of the hum.

In 1947 the body of 22 year old Elizabeth Short was found in two pieces in a parking lot in Los Angeles. According to newspaper reports shortly after the murder, Short received the nickname “Black Dahlia” at a Long Beach drugstore in the summer of 1946, as a play on the then-current movie The Blue Dahlia. However, Los Angeles County district attorney investigators’ reports state the nickname was invented by newspaper reporters covering the murder. In either case, Short was not generally known as the “Black Dahlia” during her lifetime.

Many rumours and tales have spread about the Black Dahlia, and the investigation (one of the largest in LA history) never found the killer.

The Count of St. Germain (allegedly died February 27, 1784) was a courtier, adventurer, inventor, amateur scientist, violinist, amateur composer, and a mysterious gentleman; he also displayed some skills with the practice of alchemy. He was known as ‘Der Wundermann’ — ‘The Wonderman’. He was a man whose origin was unknown and who disappeared without leaving a trace.

Since his death, various occult organizations have adopted him as a model figure or even as a powerful deity. In recent years several people have claimed to be the Count of St. Germain. (Note that St Germain was never regarded as a saint by the Roman Catholic Church – the “st.” before his name refers to his alleged home).
