Looking back at Lincoln: On April 18, 1863
On this day in 1863, Lincoln wrote the following memorandum concerning one Francis Capen, who claimed to be a "Certified Practical Meteorologist—& Expert in Computing the Changes of the Weather."
Capen was seeking work with the War Department and claiming that he could predict the weather. Lincoln obviously was not impressed:
April 28, 1863I can certainly identify with this entry.
It seems to me Mr. Capen knows nothing about the weather, in advance. He told me three days ago that it would not rain again till the 30th. of April or 1st. of May. It is raining now & has been for ten hours. I can not spare any more time to Mr. Capen.
A LINCOLN
Before the Civil War, the Army Corps of Engineers was already gathering and using weather data. When the war began - and after seeing the impact of weather on troop marches (mud) and battles (wind and rain) - battlefield commanders requested accurate weather forecasts so they could better plan their movements.
Without any legitimate meteorologists (Francis Capen appears to have been a crank,) the Army gathered weather data as best as they could, and transmitted it by telegraph (i.e. 'its raining here and the wind appears to be blowing in your general direction.') Of course this wasn't a terribly accurate way to gather and distribute weather data, but it was better than nothing.
This fledgling system evolved into the National Weather Bureau, which eventually became the National Weather Service. Now we have satellites and radar... but we here in Indiana can testify: they still get it wrong much of the time!
