The mother of all and the granddaddy of all are idioms that are very close in meaning, but with a subtle difference. We will examine the meanings of the idioms mother of all and granddaddy of all, where they came from, and some examples of their use in sentences.
The mother of all is an idiom that means the greatest, the most important, the ultimate example of something. For instance, one may say that Katrina was the mother of all hurricanes, or Amazon is the mother of all online businesses. The idiom the mother of all does not necessarily mean that something is the first; it means it is the greatest or most important. The idiom the mother of all came into use in the 1990s when it was uttered by Saddam Hussein in a speech about the Gulf War, which he called the “mother of all battles.” For the most part, the phrase the mother of all is often used in a humorous manner.
The granddaddy of all is an idiom that means the most important, the ultimate examples, the most respected of something. For instance, one may say that Oxford University is the granddaddy of all academic institutions, or that Blossom Time was the granddaddy of all musical theater. Usually, the item referred to as the granddaddy of all of something is the first or at least the first well-known of a certain category. The expression the granddaddy of all came into use in the late 1800s.

We are fortunate in the Brazos Valley to have so many community theaters: StageCenter, the granddaddy of all local theaters; The Theatre Company, purveyor of great musicals; Navasota Theatre Alliance, which does so much with its unusual stage (the audience sits on opposite sides); Troupe Over the Hill at Hilltop Lakes, which is far better than its location and budget should allow; and, the one I feel closest to, Brazos Valley TROUPE.
