In search of a new migraine medication, Albert Hoffman, a Swiss biochemist, began reacting the lysergic acid group that had been recently discovered in ergot with various reagents.  His experimentation led to the discovery of lysergic acid diethylamide, or LSD-25 in 1938.

Although LSD itself is synthetic, understanding basic knowledge of ergot, LSD’s primary derivative, is helpful to appreciate the circumstances under which LSD was created.  Ergot, a naturally occurring fungus, grows upon rye and is recognized for its medical value.  Historically, ergot has been the cause of mass poisonings across cultures (ergotism), and was also a probable cause of the Salem witch trials, as mentioned in Napoleon’s Buttons.  Beginning in the late sixteenth century, the first recorded medical use of ergot was as a drug to help with childbirth.  Unfortunately, this use was ultimately unable to be sustained, as it too often lead to uterine spasms and other dangers to the child, which are characteristics that ergot commonly shares with LSD.  As a result, it wasn’t until 1930s that this research was fully re-established, leading to the discovery of lysergic acid as the shared component of all ergot alkaloids.

HISTORY OF CIVILIZATION

• Due to humans need for water, the first civilizations were started near rivers.
  – The Nile River : Egypt
  – The Tigris and Euphrates : Mesopotamia
  – The Huang He (Yellow River) : China

  

• The need to control water for humans needs led to many different innovations that made modern civilizations possible
  – Canals, aqueducts, dams and plumbing
• Humans also made advances in civilizations by harnessing waters power
  – Waterwheel and steam engine

• Water is the most abundant molecule on Earth
  – 70% of Earth’s surface is water in liquid or solid state
  – Also found in the atmosphere as vapor
• Water is found in 75% of the body
• Even some of the driest plants on Earth are at least 50% water

• Water is essential for the survival of all known forms of life
• Water is also needed to initiate life
  Primordial Soup Theory
  – Theory on the origins of life that believes that “multimers”, chains of amino acids smaller than polymers, were the catalysts of life.
  – These multimers formed through natural chemistry with monomer amino acids in a primordial lake or pond (most likely hot acidic water with some sulphur).
  – The abundance of iron in Earth’s early stages which combined with water and ultraviolet light from the sun, would release hydrogen from the water, making it possible for amino acids to form.
  – These amino acids chains formed the first RNA which acted as both the catalyst and genes, making the organisms to duplicate on their own.*For a short clip on the primordial soup click here.
