TIL that the Zildjian cymbal company was started in Constantinople (not Istanbul) in 1623. Seriously, it is a fascinating history of a very important Turkish company whose descendants migrated to the US. Then in 1981, 3 Zildjian brothers broke off to form the rival Sabian cymbal company. Both are still family owned and operated. Now you know this too.
