Koch’s postulates (the link between microbes and diseases).

1896- The 1st vaccine for typhoid fever is made.

1897- The 1st vaccine for the plague is made.

1897- Ronald Ross shows that malaria is transmitted via mosquitoes.

1899- Felix Hoffman develops aspirin. 1900- Max Planck established the law of

Religion During this Time:

33.32% Christian 21.01% Muslim 14.09% non-religious 13.26% Hindu 12.48% other religions 5.84% Buddhist

Major Depressions and their Effect on the Economy:

Panic of 1819- was the 1st major American depression caused by a breakdown of cotton prices. Banks and farms were foreclosed because of calling in loans. It lasted until 1821.

Panic of 1837- started from the same reasons as the Panic of 1819 along with the failing of crops & problems with currency circulation. Also economic problems in Britain and land speculation. This caused the collapse of real estate prices.

Panic of 1857- stock prices plummeted due to the failure of the Ohio Life Insurance & Trust Company. The American economy was practically ruined.

Panic of 1873- the stock market was still down causing many businesses to fail. This caused 3 million people to lose their jobs, increasing poverty a lot. This led to the Populist movement which later created the Greenback party. It lasted until 1878.

Panic of 1839- this was the greatest depression known by America (it was later passed by the Great Depression in the 1930’s). The stock market completely crashed, and caused 16,000 more businesses to fail and the unemployment rate to 1 in 6 Americans losing their jobs. It lasted until 1897.

Important Scientists: Thomas Johann Seebeck

Born April 9, 1770, died December 10, 1831.He believed electric currents could be produced by temperature differences and discovered thermoelectricity (electricity produced by heat).

Andre Marie AmpereBorn January 20, 1775, died June 10, 1836.He believed in molecules and their features; described the magnetic field occurring around the conductor in which the electric current flows.

Michael FaradayBorn September 22, 1791, died August 25, 1867.He believed that the ability of space to be distempered is caused by some source. He formulated the laws of electrolysis (causes chemical decomposition by passing an electric current through a liquid or solution).

William MortonBorn August 9, 1819, died July 15, 1868.He helped discover and prove that the use of inhaled ether was an effective anesthetic.

Louis PasteurBorn December 27, 1822, died September 28, 1895.Although he loved science, he stated that he had ‘absolute faith in God and eternity’ anf he believed that ‘the power for good given to us in this world will be continued beyond it.’ But he never let his science and religion mix.He discovered the pasteurization process (the sterilization of foods), founded the science of microbiology, and discovered many vaccines, including rabies.

Robert KochBorn December 11, 1843, died May 27, 1910.He helped discover the science of microbiology and established Koch’s postulates. He also discovered the agents that cause tuberculosis, cholera, and anthrax.
