I'm sorry that I didn't answer this morning, but I thought my reply would have been lengthy and I read your question just a few minutes before 8 AM. I will have to say that I agree with all of the replies above. The architect was Wyatt C. Hedrick in collaboration with Alfred Finn. Finn got his start at Sanguinet & Staats, but in 1913, quit the firm to go into business for himself. He set up his shop in Houston and designed some of the city's iconic buildings, including the Rice Hotel and the Gulf Building. He designed many of Jesse Jones' buildings in Texas. The information on the architects of the building is listed in the Tallest Buildings in Fort Worth.
I'm pretty sure that the closure and the demolition took a lot of activity out of that part of downtown. From the 30s until the 70's there were three big movie theaters on West 7th Street. I think in the 60's they were in decline because my family made sure that I got to see at least one movie in each of the big theaters in downtown before they closed. The Worth, which was situated behind the tower of the Worth Hotel was the grandest of the three movie houses on 7th Street. The big 6 1/2 story sign was for the theater. The hotel had a rather small entrance right in the center of the building. As I remember, the building was similar in layout to the Electric Building. The lobby of the theater was inside the tower portion of the building. I do remember the hotel being in rather bad shape when I was a kid and that was the reason they used to justify demolishing the building. The Fort Worth Club bought the building and then demolished it, but I'm not sure on the exact timeline. I do remember the implosion back in 1972. It was the first building implosion in Fort Worth and I was a freshman in high school. I have a brick from the building sitting just a few feet away from me right now. I also can't remember the timeline of the theater closures. I do know that the Hollywood was open the longest. Even though the Worth was the grandest on 7th, supposedly the Majestic was the grandest theater in the city. Unfortunately, I never had the opportunity to see a movie in the Majestic because it was either closed, or a place a kid wasn't allowed inside when I was old enough to go to the movies. I do remember its demolition back in 1965, or so.
I do agree that the Worth Hotel was a better building than the Fort Worth Club Tower that replaced it. If you look at the list of tallest buildings, you see that the Fort Worth Club replaced the hotel with a building of almost exactly the same height.
