The 1946 founding and the original Munger and Moss families
The Munger Moss Motel opened in 1946 — the same year Route 66 traffic began rebounding from the wartime fuel rationing of the early 1940s and a period when motor-court construction along the Mother Road was at one of its all-time peaks. The original owners were two business partners, Pete Munger and Emmett Moss, whose surnames produced the property's distinctive name. Both men had operated a small Route 66 sandwich shop in nearby Devil's Elbow (roughly 35 miles east) before deciding to consolidate their savings and build a proper motor court in Lebanon, which by the mid-1940s was emerging as one of the standard overnight stops on the Chicago-to-Springfield-Missouri leg of the highway.
The original Munger Moss was a fairly typical mid-1940s Route 66 motor court — a row of small detached cabins arranged in an L-shape around a gravel parking court, with a separate office building near the highway frontage. Cabin construction was wood-frame with painted clapboard siding; each unit had a single bedroom, a small private bath, and a covered parking slot adjacent to the door. The location on the eastern edge of Lebanon was strategic: travelers arriving from the east at the end of a long Ozark driving day could pull off the highway immediately upon entering town without having to navigate Lebanon's downtown grid.
Pete Munger and Emmett Moss sold the property in the early 1950s; the motel changed hands several times across that decade as the original cabins were gradually replaced with the longer row-style guest wing that still defines the property today. The 1950s renovations also added the iconic neon sign — the exact installation year is somewhere in the 1955-to-1957 range, with surviving documentation slightly ambiguous, but the sign has been a continuous feature of the property since at least 1957 and was prominently included in late-1950s Route 66 tourism photography.
