A baker is a tradesperson who bakes and sometimes sells breads and other products made of flour by using an oven or other concentrated heat source. The place where a baker works is called a bakery.Since grains have been a staple food for millennia, the activity of baking is a very old one. Control of yeast, however, is relatively recent.[1] By the fifth and sixth centuries BCE, the ancient Greeks used enclosed ovens heated by wood fires; communities usually baked bread in a large communal oven.[1] Greeks baked dozens and possibly hundreds of types of bread; Athenaeus described seventy-two varieties.[2] [Wikipedia]
