The partnership was later expanded to include architects Noland Blass Jr., Lugean L. Chilcote, Jerry C. Wilcox and others.
They later proposed to buy shares of the firm, which was refused by Stern, and in 1930 they left to establish the partnership of Erhart & Eichenbaum.
[1] Depression-era projects included three county courthouses and a major expansion of the Arkansas Tuberculosis Sanatorium.
Blass' major projects for the firm include the former Veterans Administration Hospital (1950), the UAMS Medical Center (1956), the Justice Building (1957) and Bank of America Plaza (1969) in Little Rock and the George Howard Jr. Federal Building and United States Courthouse (1967) in Pine Bluff.
Erhart and Rauch had retired by 1970, and new partners by that time included engineer Edgar K. Riddick Jr. and architect Lugean L.
In 1976 the firm was renamed Blass, Riddick, Chilcote and the partnership was expanded to include engineers Gulley Carter and Richard L. Lanford and architect Jerry C.
The local partner, after the retirements of Harold and Allen Casey, was Charles C. Hill Jr.[8][9] Lanford and Wilcox withdrew in 1985 and 1988, respectively, and the firm was renamed first to Blass, Chilcote, Carter & Wilcox and second to Blass, Chilcote, Carter, Gaskin, Bogart & Norcross.
[13] The Arkansas firm was dissolved after the death of then-president Gaskin in 2007, leaving GHN of Springfield as the successors to the Erhart & Eichenbaum legacy.

He worked for Little Rock architects Ken Cole Jr. and Swaim & Allen until 1958, when he joined Erhart, Eichenbaum, Rauch & Blass.
