The history of Cologne

Eau de Cologne (or Water from Cologne) was created by perfumer Johann Maria Farina of Cologne, Germany in 1709. Its name has ever since come to be used as the generic name for scented formulations.
His original formula contained a mixture of oils of lemon, orange, tangerine, clementine, bergamot, lime, grapefruit, blood orange, and bitter orange. It can also contain oils of neroli, lavender, rosemary, thyme, oregano, petitgrain (orange leaf), jasmine, olive, oleaster, and tobacco.
On creating his signature formulation he stated, "I have found a fragrance that reminds me of an Italian spring morning, of mountain daffodils and orange blossoms after the rain,"
