Dive Flag Origins

The now-familiar red-and-white dive flag was invented in the early 1950’s by Denzel James "Doc" Dockery from Michigan.
Dockery was a tinker and entrepreneur. In 1953, he followed instructions published in Popular Science magazine for building his own scuba unit, and began experimenting with ways to make a living in the brand new sport.
In the course of his work, Dockery found that he needed a warning flag to keep boaters at a safe distance. Since Dockery had served in the U.S. Navy, he was familiar with the red signal flag that’s commonly used to connote danger. The Navy’s "bravo flag" is solid red
In order to make his flag distinctive, Dockery decided to make a modification. He asked his wife Ruth to sew a white stripe across the middle of it. They put their stripe horizontal, right down the center from left to right.
Unfortunately, there was a problem with their design. It was the national flag of Austria. They needed something else. A vertical white stripe was out since that’s the Navy’s numerical number 7 signal flag.
After doing their homework, they decided to make the stripe diagonal. Ruth sewed it from the upper-left corner to the lower-right corner. The dive flag, as we now know it, was born.
Of course, inventing a flag is one thing. Getting it used and recognized is another.
Perhaps more important than his role in creating the dive flag was Dockery’s evangelism for it. With the persistent tenacity of a good entrepreneur 2 Dockery began selling flags and promoting their use.
In 1956, Dockery’s flag got a major boost. Ted Nixon from U.S. Divers started buying them from him and distributing them nationally. Nixon became so instrumental in the flag’s widespread adoption that many people mistakenly credit Nixon with inventing the flag.
Another boost came from Skin Diver magazine. They mentioned Dockery’s flag in a September 1957 editorial and asked their readers to send in their thoughts on the design. In February 1958, they declared the discussion closed, with the "Michigan Divers Flag" as the reader’s choice. 3
