The Greek engineer Ctesibius of Alexandria is credited with inventing the organ in the 3rd century BC. He devised an instrument called the hydraulis, which delivered a wind supply maintained through water pressure to a set of pipes.

In the Scots language - A kist o' whistles is a derogatory name for a church organ. The phrase was used by those opposed to the use of musical instruments in church. But is also means a person with a wheezy chest.
