On June 8, 1922 after an rain-soaked fraternity game at the field, a student living on Breese Terrace called the fire department and reported seeing flames at Camp Randall. By the time the fire department arrived the old wood grandstand was engulfed in flames, and far beyond saving. No certain cause of the blaze was ever determined, it was variously blamed on arson, a cigarette, town kids, et.al. Ironically the building had been sold the previous day to a salvage man. Thus passed the last remnants of the old stadium where played the earliest greats of the Badger football program, fabled "kangaroo" kicker Pat O'Dea, J.F.A. "Sunny" Pyre, "Norsky" Larsen another member of the conference champion teams of 1901 and 1912.
In July of 1923 work was under way on concrete bleachers for the east side of the field that would add 5000 more seats to the stadium (Arthur Peabody's design). The temporary north bleachers were replaced with concrete in 1923 also. By 1924 the capacity of the stadium was listed as 33,000. For the next fifteen years the bowl-shaped stadium grew bit by bit as money became available from the legislature or from gate receipts. In 1940 an addition was built that completed the original bowl. It now wrapped around the field on three sides, with the field house filling in the south end, which had originally been left open to alleviate the ventilation problems that early stadia of this type exhibited. It had a capacity of 45,000 and utilized some temporary bleachers on the northwest and southwest corners.
An interesting aspect of the Camp Randall stadium was the inclusion of the stadium dormitories. In the period around 1940 housing for students and military personnel was a distinct problem in Madison, and the regents sought innovative ways to alleviate the problem. The '1940' addition (designed by the state Bureau of Engineering) which was actually begun November 1939, added 7500 seats on the east side and built the dormitory under the east side seats. The outside wall was sheathed with Madison sandstone (for which a local quarry had to be temporarily reopened), and in addition to the dormitory for 150 men, there were boxing and wrestling quarters, and a rifle range. The work on the 1940 addition to the stadium was done by the WPA (Works Progress Administration) a depression era federal program.
