….................... had written a short history of the crises in the 19th Century in 1892a.Karl Marxb.Adam Smithc.Henry Hyndmand.Johann Silvio Gesell

The question is asking to identify which individual authored a short history of the crises in the 19th Century in the year 1892. Let’s analyze the options provided:

1. Karl Marx: A prominent philosopher and economist known for his theories on capitalism and class struggle. Marx wrote extensively about economic crises, particularly in his works such as "Das Kapital."

2. Adam Smith: Often referred to as the father of modern economics, Smith wrote "The Wealth of Nations," focusing on the nature and causes of wealth. However, he lived in the 18th century and passed away in 1790, which makes it impossible for him to have written anything in 1892.

3. Henry Hyndman: A British socialist politician and writer, he published "The Historical Basis of Socialism" and was involved in various socialist movements. He is known for discussing economic crises in context but is not primarily known for summarizing history in 1892.

4. Johann Silvio Gesell: A lesser-known economist and social theorist, Gesell is known for his theories on free money and economic cycles. He wrote about economic issues in the early 20th century but his works do not prominently feature a historical analysis of crises in the way the question suggests.

Given this information, the most likely candidate who wrote a short history concerning economic crises in the late 19th century is Karl Marx, considering his focus on the analysis of capitalism and its inherent crises. Hence, I would conclude:

Final Answer

a. Karl Marx
