Nido was born and raised in the town of Arroyo in Puerto Rico. There he received his primary and secondary education. In 1938, he enrolled in the University of Puerto Rico and studied mechanical engineering in the institution's Mayagüez Campus. During his days as a university student, he decided that he would like to become an aviator for the United States Armed Forces. After he earned his college degree, Nido traveled to the island of Saint Thomas of the U.S. Virgin Islands with the intention of joining the United States Naval Aviation. Nido passed the physical examination, however he was denied acceptance into the aviation program because of a minor dental problem. According to the examining medical doctor, the fact that he had one tooth that grew above another would make it impossible for him to fly in high altitudes. He then traveled to Washington, D.C. and attempted to join the armed forces there. After passing the physical examination, he was again denied acceptance, for the same reason. Nido then traveled to Tulsa, Oklahoma and enrolled in the Sparton School of Aviation where in 1941, he received his pilot's certificate.
Military career
After he graduated, he was given a job as an aviation instructor in the institution. An officer of the Royal Canadian Air Force who was in Tulsa looking for recruits asked Nido to consider joining them. Nido accepted the offer and on September 1941, he received a telegram from the RCAF office in New York City, requesting his presence at the Waldorf-Astoria Hotel. Nido traveled to New York and on 7 September, was sworn in as a member of the RCAF. After 3 months of intense training in Canada, Nido was commissioned a Flying Officer and sent to an air base in Quebec, where he served as an aviation instructor to bomber pilots and artillery gunners. Nido returned to his homeland, to spend 15 days with his mother and three brothers Rafael, Pedro and Thomas, who were members of the United States Armed Forces. During his stay he met his future wife, Alile Colon, a university student at the "Colegio del Sagrado Corazon", from the town of Yabucoa.
World War II
On 24 December 1942, Nido was sent to London, England, and participated on the European Theater of the war as a bomber pilot. He was transferred to 610 Squadron of the BritishRoyal Air Force and participated in various combat missions as a Supermarine Spitfire pilot. In November 1943, Nido, then a Captain, was among 10 pilots of the 67th Reconnaissance Squadron who were sent to weather school at RAF Zeals under the command of Colonel T. S. Moorman. His unit participated in 275 missions. Later, in 1943, Nido and 59 other American pilots were transferred to the U.S. Army Air Forces. He was assigned to the 67th Fighter Group as a P-51 Mustang fighter pilot. Nido baptized his P-51 with the name of "Alile" in honor of the girl that he left back home.
Post World War II
After the war he continued to serve in the Army Air Forces and in 1947 became part of the newly formed United States Air Force. On 23 November 1947, the Puerto Rico Air National Guard came into existence as a result of the efforts led by Colonel Alberto A. Nido, Colonel Mihiel Gilormini, and Lieutenant ColonelJosé Antonio Muñiz. Nido served as commander of PRANG for many years and was later assigned to the National Guard Headquarters as Chief of Staff for Air. In January 1966, Nido, approached Maj. Gen. Winston P. Wilson, Chief of the National Guard Bureau, inquired about the possibility of constructing a range at the Army Guard's Salinas Training Area, located 35 miles on the south coast area of Puerto Rico. Two days later, Brig Gen. Salvador Roig approved a plan for this project and assigned Captain Gabriel I. Peñagarícano as project officer. The NGB budgeted $10,000 for this construction, this tight budget required a maximum in-house effort. The U.S. Army Antilles Command, caretakers of the Salinas Training Area, provided earth-moving equipment and personnel to level the target area. They also dug necessary holes for electric power poles, communications and strafing and skip-bombing targets. The range towers were donated by the air depot at McDill AFB and transported directly to the range on C-123 aircraft. Nido, who also served as commander of the local chapter of the "Military Order of World Wars", retired from the military with the rank of Brigadier General in 1974. On 27 October 1991, Nido died in San Juan, Puerto Rico and was buried with full military honors in Plot: J 9 of the Puerto Rico National Cemetery in Bayamón, Puerto Rico.
