Who was the first Medal of Honor recipient to receive his medal at the White House?
There appears to be a lot of confusion about the answer to this question. It seems that the first person to actually receive his medal at the White House was Silvestre S. Herrera, on August 23, 1945. It was presented to him by Truman. Before this, no medals were actually given at the White House.

Who was the first Medal of Honor recipient to receive his medal at the White House?
Let me add more confusion to this answer.
"The War Department moved into a comparable structure northwest of the White House, north of its old location where the Navy Department remained in the Southwest Executive Building. It also occupied the Winder Building across the street after it completion in 1848. During the Civil War, Secretary of War Edwin M. Stanton added two floors to the War Department building. Abraham Lincoln would walk over from the White House to get updates from the War Department telegraph operators in the Army's headquarters....
In 1870, the US Congress decided to construct a new building west of the White House to house the State War, and Navy departments."

Parrott most likely received his medal in the War Depart building and not the White House. Is Robert E. Cox the first to receive his medal in the White House as my first link mentions? (serpa)

Does the length of a nautical mile (which, by definition, is based on the curvature of the earth at sea level) change with altitude? In other words, is a nautical mile the same length for an aircraft flying at 30,0000 feet as it is for an ocean liner?
A nautical mile is slightly longer at altitude: [quote]nautical miles are defined as 1,852m wherever you're using it. But I do sort of see what you mean; if you look at the relationship between minutes of latitude and nautical miles, then it's only exact at sea level. However, the difference is tiny. There are around 21,600 nautical miles in the Earth's circumference, and that figure increases by 2? nautical miles for every nautical mile of altitude. To make a 1% difference (216nm) you'd need to fly at around 35 nautical miles; most jet aircraft fly at 4-6nm. Generally you're flying from land, to land. So the difference goes away as you descend anyway.[/quote] https://www.quora.com/While-flying-why-is-the-airplane-still-using-nautical-miles-Isn-t-the-value-of-nautical-miles-larger-at-a-higher-altitude-than-on-Earths-surface-How-can-they-compensate-for-this

Yes, there is a standard length for a "Nautical Mile" and it does not vary based on altitude. The "Nautical Mile" is based on the "Grid System" of Latitude and Longitude, although Longitude isn't really considered.
[quote]A nautical mile is slightly longer than the standard, or "statute," mile we use in our daily lives, coming in at approximately 1.1508 land miles. However, this isn't just an arbitrary difference. The nautical mile has its roots in the very shape of our planet. Based on Earth's longitude and latitude coordinates, 1 nautical mile corresponds to one minute of latitude. One minute of latitude is about 1.1 miles (1.8 kilometers) and one second of latitude covers about 105 feet (32 meters).
In the English measurement system, there is 1 nautical mile per 1.1508 land miles or 6,076 feet. One nautical mile is a length equal to 1,852 meters, or 1.852 kilometers.
The primary reason for using a different measurement system for marine and aviation navigation relates to the curvature of the Earth. As you embark on long-distance travel, Earth's round shape becomes a factor in accurate measurement. Nautical charts employ latitude and longitude, making it much simpler for mariners, pilots and astronauts to measure distances using nautical miles, offering a more precise representation of the route traveled.
A nautical mile is based on the circumference of planet Earth. If you were to cut Earth in half at the equator, you could pick up one of the halves and look at the equator as a circle. You could divide that circle into 360 degrees. You could then divide a degree into 60 minutes. A minute of arc on the planet Earth is 1 nautical mile. Nautical miles as units of measurement are used by all nations for air and sea travel.[/quote]

Parrott's wikipedia page says Secretary of War Edwin M.Stanton presented the medal to him.
"The Great Locomotive Chase; a History of the Andrews Railroad Raid into Georgia in 1862," 1889. William Pittenger mentions "they were in the ante-room waiting" (page 411). Parrott was presented the medal on page 413.
