Born on May 7, 1892 in Morong, Philippines, Private Tomas Mateo Claudio is one of the few Asian Pacific Americans known to have served in the First Division (later First Infantry Division) during World War I. In fact, he is believed to be the only Filipino American to serve in the BRO during that time.

Tomas immigrated to Hawaii in 1911, subsequently traveled to Alaska and ultimately made his way to Nevada. In 1917, Tomas enlisted in the U.S. Army and joined K Company, 28th Infantry Regiment, First Division, in France.
On June 29, 1918, the sole Filipino combat casualty in WWI died in service with the First Division while it held positions in the Montdidier sector. In General Orders No. 1 issued 1 Jan 1920 by HQ First Division, T. M. Claudio is cited for gallantry in action.

In 1921, Tomas Claudio’s remains were returned to the Philippines and re-interred at Manila North Cemetery. Afterwards, a school in Morong was named after Tomas. It is now known as the Tomas Claudio Memorial College.
Tomas Mateo Claudio’s story reveals a little-known aspect of military history, that Asian Pacific Americans served integrated throughout the force during World War I, and long before World War I.

From Postiviely Filipino Website:
Claudio was born May 7, 1892 in Morong, Rizal. He did not finish high school; so he started working early as a guard at the Bureau of Prisons. In 1911, hearing from friends of opportunities in Hawaii, the young Filipino set out for Honolulu. There, he tried his luck at working in the fields.
Although earning in dollars, he found the situation not to his liking and sought adventure elsewhere. He moved on to a salmon cannery in Alaska, before ending up in Reno, Nevada. There, he enrolled in courses at the Clark-Heald’s Business College, which enabled him to join the US Postal Service. By then it was 1916, and the “Great War” in Europe was raging into its 3rd year.
By 1917 the US joined the war. Heeding the call for more adventure, Claudio tried to enlist with the US Army. He succeeded on his third attempt and was assigned to the Army’s 41st Division. He was now a Yankee doughboy. By December 1917, the boys were shipped off to France. Claudio was transferred shortly to the 28th Infantry Regiment, which fought at Cantigny. In late June 1918, he was badly wounded in combat.
On June 28, 1918, Pvt 1st Class Tomas Claudio, 26, died of wounds sustained in battle It was not until 1921 when his remains were repatriated to the Philippines. Ten years after he first left home, Claudio, finally came back and was laid to rest at Manila North Cemetery.

Other local honors came soon. A new elementary school in his native Morong, Rizal, was quickly renamed after the hometown hero. Today, it has grown and is now called the Tomas Claudio Memorial College(s), offering up to graduate degrees in business and education.
