Anna Morris Holstein (née, Ellis; pen name, Mrs. H.; April 9, 1824 – December 31, 1900) was an American organizational leader, civil war nurse, and author.

Largely through Holstein's influence, George Washington was able to purchase his headquarters at Valley Forge, which have been restored and are now accessible to the people as a historic location.

[1] Her publications included Three years in field hospitals of the Army of the Potomac (1867), Swedish Holsteins in America from 1644 to 1892 (1892), and Valley Forge : Winter of 177–78 The Darkest Period of the Revolution (published posthumously, 1903).

Her grandfather, Richard Wells, though an Englishman of noble descent, was commissioned to provision the U.S. fleet on the Delaware River during the American Revolutionary War.

On June 14, 1863, she started with the hospital train, which was 20 miles in length at Fairfax Court House, when the army began moving north toward Pennsylvania.

As soon as Camp Letterman, the general hospital at Gettysburg, was established, Holstein was made it matron-in-chief by Dr. Cyrus Nathaniel Chamberlain.

Her served at Sharpsburg, Falmouth, Hancock's Division Hospital, Belle Plain, Port Royal, White House, and City Point in the American Civil War.

Anna led them on their mission to save, acquire, restore and preserve General Washington's Valley Forge Headquarters and surrounding acreage as parcels became available.

[7] To help create awareness and raise needed funds, they organized a large event that was held on June 19, 1878, to commemorate the 100th anniversary of the Army of The Revolution departing Valley Forge.
