When Project Y came to town, every ranch school structure that could serve a purpose was put into use. The Pyramid of Los Alamos aka Spruce Cottage became the “WAC Shack”. The ladies of the “Women’s Army Corps” enjoyed their stay at Spruce Cottage. With it’s sprawling group of cozy rooms, Spruce Cottage was home to a group of young women instead of the young men who had occupied it for so long. Not that Spruce Cottage didn’t see it’s share of young men, the WAC Shack was a popular place for enlisted men to hang out in the off duty hours.

Sometime in 1943, plans were put in place to build a larger dormitory for the WAC unit stationed in Los Alamos. At the peak of their effort, there were 260 WACs here in Los Alamos. Most of the WACs were stationed at Los Alamos and Oak Ridge. There were smaller units at other Manhattan Project sights, and the largest unit of 275 were at Oak Ridge, Tenn. The “new” WAC Shack is still here in Los Alamos in its original location over on 17th Street. This building is currently under consideration for restoration with Los Alamos County. You can see more about this project HERE. There’s a lovely photo gallery of this building by Minesh Bacrania which is part of the “Behind the Fence” project which you can view HERE.

With the new WAC Shack in use, Spruce Cottage was split into three separate apartments. Thanks to the sprawling floorplan of the cottage, Spruce Cottage now known as T-115, had three different street addresses!

That bathtub so appreciated by the WACs, (who would’ve only had showers in their new dormitory), actually became quite the bragging point to anyone occupying the stone portion of the old Spruce Cottage. Kenneth Bainbridge and his family often allowed their friends to have a soak in their large, private bathtub. Kenneth Bainbridge was the physicist who took charge of the running of the Trinity site test.

You might imagine that when the Army remodeled Spruce Cottage after the WACs moved out, they did so as quickly as possible. Apparently this ended in some typical housing features being forgotten. Nathan and Elinor Ramsay were given an apartment created from the old boys dormitory section of Spruce Cottage. But when the Army put the apartment in, they forgot any closets. The Ramsays hoofed it over to the former Chief Mechanic’s House and borrowed two hand decorated wardrobes, which they utilized as closets until the Army remodeled Spruce Cottage yet again after the Fuller Lodge expansion.

Post War, circa 1948, Spruce Cottage was reconfigured into two apartments, duplex style. The end result left a “stone half” and a “wooden half”. The families of Jerome Kellogg and John Manley discovered that while they occupied two separate “homes”, they had no choice but to cooperate. Both apartments shared a hot water heater and a furnace. Can you imagine what that might be like? Good Neighbor behavior would take on a whole new meaning!

Stanislaw and Francois Ulam occupied the stone half of Spruce Cottage beginning in 1949. It is said that Stanislaw Ulam was sitting in the kitchen of the stone half of Spruce Cottage when he thought of a way to make the “Super” bomb work. His wife reported coming home and finding him sitting in the kitchen having his lunch while staring out the picture window with a strange expression on his face. While Ulam did indeed make a discovery that led to the development of thermonuclear weapons, his wife recalled later that she was appalled and had hoped the “Super” bomb would never successfully work.

In the summer of 1950 & 1951, Enrico and Laura Fermi rented the wooden half of Spruce Cottage. By 1951, James and Betty Lilienthal had begun to rent the stone half. When the dispersal of housing in Los Alamos began in 1969, the Lilienthals purchased both the stone half and the wooden half and returned Spruce Cottage to a single dwelling. Many folks in Los Alamos still think of Spruce Cottage as “the Lilienthal House”. The house was purchased by Bart and Colleen Ollinger in 1996 and has been preserved and appreciated by the long time Los Alamos residents ever since.

I love the long history of some of these old buildings in Los Alamos. It’s such a great thing to see that one of the most consistent parts of life in Los Alamos through the years is the ability to change with the times. I often hear from newcomers that they wish Los Alamos could get a this or a that. I remind folks that it’s best to just sit back and see what Los Alamos has brewing. Every decade seems to bring in a new mixture of activities, businesses, opportunities, and amenities. And when YOU’RE ready to join our community on the hill, give me a call! I’d love to chat Los Alamos Real Estate with you.
