So many assemblies, play, recitals, and community events have taken place in this building!

The Los Alamos Historical Society was saddened to learn of the recent passing of long-time Los Alamos resident Rita Martinez Apel. Mrs. Apel arrived in Los Alamos in 1947 as a young woman and worked as a waitress and hostess at Fuller Lodge, living for a time in the staff quarters on the second floor. She was also crowned Snow Queen at the Army-Navy Club Snow Ball, held on December 3, 1948 in Los Alamos. These photographs from our collections show a lovely young woman at the beginning of a long and wonderful life in Los Alamos. The Los Alamos Historical Society Archives & Collections are lucky to have an oral history interview with Rita Martinez Apel and her husband Charlie Apel in our collections. Our heartfelt condolences go out to Mrs. Apel’s family and friends.

On this day, June 10, 1949 Los Alamos County was established! During the war and those first years after Los Alamos remained federal property and not considered part of New Mexico. This caused difficulties for residents to vote in elections. Finally in 1949 Los Alamos County was created as an official county in New Mexico.

📸1: Governor Thomas Mabry pointing out the new tiny County of Los Alamos on a map showing the counties of New Mexico. Three men representing Los Alamos are holding a poster commemorating Los Alamos’ new status. George Work is standing on the far right holding one corner of the Los Alamos poster. Earle Sullivan, 2nd from the left, represents the Atomic Energy Commission. The poster features an artist’s rendition of the mushroom cloud at the Trinity Test. Los Alamos officially became a county on June 10, 1949.

📸2: In this 1967 view, the new Los Alamos County Municipal Building sits at the center of the frame. To the right is the old Los Alamos County government building. The photographer is standing on the south side of Trinity Drive, which passes through the foreground of the picture. One of the peaked roof Sundts appears on the far left side of the frame.

📸3: Part of the Disposal process for Los Alamos in the 1960s included the design and building of a new center for local government. Paid for by the Atomic Energy Commission, this building was known as the Los Alamos County Building or the Los Alamos Municipal Building. This scene records the dedication of this building on the west side of Ashley Pond, June 24, 1967.
