shape of a Maltese cross. In 1919, the building was taken over by the Army and converted into a service club. Today, it is used as office space, a meeting area and more. Pershing Hall The original and present-day bachelor officers' quarters (Building 16) was completed in 1904. This facility was originally given the number 16 to incorporate the structure with the numbering system for the 19 sets of quarters on Staff Row, numbered 1 through 20, which is the reason why there is no number 16 on Staff Row. This building was named in honor of General of the Armies of the United States John "Blackjack" Pershing. During his career, Pershing served as the commander-in-chief of the American Expeditionary Forces in World War I and later as the Army chief of staff. Van Horn Hall Completed in 1889 as the original post headquarters, this two-story structure (Building 41) contained office space for the commander, adjutant, sergeant major, clerks, library, mail and court martial room. In 1891, the first rental of a telephone line to Atlanta for $12.50 a month was authorized. In 1893, $17 was approved for material and labor to install electric bells and connections in the building to facilitate communication and the transaction of business in the headquarters. Thus, the first known "intercom" system was installed on post. This building was named in honor of Brig. Gen. Robert O. Van Horn, who served as post commander from January 1934 until August 1940. This six-and-a-half-year period is the longest post commander's tour in the installation's history. In 1957, the building became office space for the staff judge advocate. Staff Row Staff Row consists of 19 officer quarters — four single-family residences and 15 duplexes. These quarters were built from 1891 until 1910 at an average cost of $15,000. The original concept for Staff Row was to build homes for the officers of an artillery regiment with 10 batteries. At full strength, such a unit would be authorized a colonel, a lieutenant colonel, three majors, 10 captains, 20 first lieutenants and 10 second lieutenants. The final home built on Staff Row in 1910 is currently the residence of the post commander. The small lot required that Quarters 18 also be a single-family unit. Hedekin Field Staff Row faces the post parade ground, Hedekin Field. Originally a polo field, it is named in honor of Capt. David Drew Hedekin, an
