In looking at Cliff May's Issue Date, January 01, 1986, here is what I think was going on. I used a Building Designer in the 60s, she held a degree in architecture from Cal Berkeley but upon graduation she went right to work as a Building Designer, I never asked her but I assume that she didn't want put in the 5 years of slavery required of all aspiring architects in order to provide free labor to architects. She held RBD #22, at some point the state froze the program allowing existing RBDs to continue to practice but not allowing any more. Somebody, whether it was the state or the AIA, decided to end this and all active RBDs were grandfathered in as architects. Recently I saw that her work was honored by a society of Woman Architects and they were categorized by the name of the client, looking through the list my name was absent; however, my long-time foreman's name was listed for several of his homes. What I surmised was happening was that all of my projects were back when the RBD program was active, and my foreman's projects were built after she was grandfathered in as an architect, I went to visit her not long before she passed and she told me her favorite house was my Bruener home, it was built in 1975 when she was still a RBD..
Notice that her archives start in 1981.
