Major Harold C. Geiger (October 7, 1884 - May 17, 1927), born in East Orange, New Jersey, was a pioneer in US military aviation and ballooning who was killed in an airplane crash in 1927. Spokane International Airport is designated with the International Air Transport Association airport code GEG in his memory.

Geiger was a Cadet at the United States Military Academy June 16, 1904 to February 14, 1908, when he was graduated as an Army Second Lieutenant in the Coast Artillery Corps. He was promoted to First Lieutenant November 8, 1908.

As a lieutenant, Geiger commanded the aviation assets of the United States Army Signal Corps in the Hawaiian Islands. The first Army airplanes, pilots and crews arrived in Oahu in July 1913. The planes were based at Fort Kamehameha, near present-day Hickam Air Force Base.

Lieutenant Geiger arrived in Oahu with two Curtiss Aeroplane Company seaplanes, a mechanic, 12 enlisted men, and other equipment. However, Geiger’s aircraft were in poor shape. His flights were limited to short flights in Pearl Harbor and a longer flight to Diamond Head, Hawaii and back to Fort Kamehameha.

Teddy Geiger (born John Theodore Geiger II on September 16, 1988) is an American singer-songwriter and occasional actor. He is known to play the guitar, bass, piano, drums and trombone.

In November 2011, Teddy announced that he is recording and releasing an exclusive new album The Last Fears through PledgeMusic.com.

Teddy Geiger was born in Buffalo, New York, later moving to Rochester, New York. He wrote his first song at the age of 10. Raised a Roman Catholic, Geiger attended McQuaid Jesuit High School through his junior year.

His first band was formed in 2005 under the name "Faction". This band played at several venues in Rochester, New York, winning a "battle of the bands" competition at the Water Street Music Hall. The band was headlined by Geiger's lyrics, vocals, guitar, and keyboard; other band members included drummer Ben Harmon, lead guitarist John Ryan, and bassist Daniel Beale. The band broke up in early 2005, following Geiger's signing with Columbia Records.

Teddy Geiger was first seen in national media as a finalist in VH1's In Search of the Partridge Family and earned credibility when touring with Hilary Duff as the opening act for her summer 2005 tour Still Most Wanted. His first single, "For You I Will (Confidence)", was officially released in February 2006. The song received positive reviews, being called "sweetly romantic" and said to contain "sophisticated lyrics", besides being nominated for "Best Love Song" in the 2006 Teen Choice Awards.
