This was a WONDERFUL article on the generation of studio logos. I am an art director designing film props and have been in the biz since '73 so I have been fortunate to have met some of the artists responsible for the logo work we see in film openings.
What you have identified as the 4th Warner Brothers shield logo was created by Louis Fox, a staff artist at Warner Brothers at the time. Mr. Fox worked into his 80's and was last known for doing the large art signs for "The Price is Right".
Also FYI the Universal chrome globe with the plane circling it and the rotating stars was done by John Harkrider, who worked in the scenic, art direction, costuming and set design field, having come from New York where he designed sets for Florenz Ziegfeld.
