Ashford (September 28, 1873 – September 10, 1934) was an American physician who had a military career in the United States Army, and afterward taught full-time at the School of Tropical Medicine, which he helped establish in San Juan.
A pioneering physician in the treatment of anemia, while stationed in Puerto Rico Ashford organized and conducted a parasite treatment campaign against hookworm, which cured approximately 300,000 persons (one-third of the Puerto Rico population).
This reduced the death rate from associated anemia by 90 percent.
He was a founding member of the Puerto Rico Anemia Commission.
