McLeod syndrome was discovered in 1961 and, as with the Kell antigen system, was named after the first patient in which it was found: a Harvard dental student Hugh McLeod, whose red blood cells were observed to have weak expression of Kell system antigens during blood donation, and his red cells were found to be acanthocytic (spiky) under the microscope.

Famous quotes containing the word history:
““And now this is the way in which the history of your former life has reached my ears!” As he said this he held out in his hand the fatal letter.”

“You that would judge me do not judge alone
This book or that, come to this hallowed place
Where my friends’ portraits hang and look thereon;
Ireland’s history in their lineaments trace;
Think where man’s glory most begins and ends
And say my glory was I had such friends.”
—William Butler Yeats (1865–1939)
“Let us not underrate the value of a fact; it will one day flower in a truth. It is astonishing how few facts of importance are added in a century to the natural history of any animal. The natural history of man himself is still being gradually written.”
—Henry David Thoreau (1817–1862)
