Golf Tee

Grant claims "a rigid base portion a and an attached flexible head b". Two materials doing opposite jobs — one must hold still, the other must give way.

Mould ten cones of damp sand by hand and measure the height of the ball on each. Record the spread — that variation is the problem.

Note the total time, and that you needed sand, water and both hands. On a course this happens on every tee, for every player.

Shape a hardwood peg about 60 mm long, tapering to a point at one end so it pushes into turf without splitting it.

Turn a shoulder down near the head so the rubber tube can be pushed on and seat against it. The patent specifies this reduced section.

Push a short length of rubber tube onto the reduced top so it stands proud and forms a small cup for the ball.

Build a control with a solid wooden head instead of the rubber. You now have the two designs the patent distinguishes.

Push each into turf and measure the ball's height ten times. Compare the spread against step 2. Repeatability is the first gain.

Take a slow, controlled swing across the rigid tee at model scale. The head strikes the post and the post fights back — note the deflection and the mark on the club.

Same swing, flexible head. The rubber folds over in the direction of travel and springs back. The club passes as if the tee were not there.

After the flexible strike, the base is still in the ground and the head is upright again. A tee that survives is a tee you do not replace every shot.

Push the tee in at three depths and measure ball height for each. Height is now a decision the player controls, not an accident of how the sand piled.

The patent. US 638,920, "Golf-tee", filed 1 July 1899 and granted 12 December 1899 to George Franklin Grant of Boston.

Grant was not a golf professional; he was a dentist, and a notable one. He graduated from Harvard Dental School in 1870 as one of its first African American graduates, became Harvard's first African American faculty member, and specialised in treating cleft palate, for which he designed a prosthetic appliance. Golf was a hobby, and the tee was a hobbyist's fix for an irritation — he had them made and gave them to friends.

⚠ He never commercialised it, and that matters for how the story is told. Grant's tee did not take the market. The tee that did was the "Reddy Tee", patented by another dentist, William Lowell, in the 1920s — a simple painted wooden peg, aggressively marketed by paying touring professionals to use it. Grant's priority went largely unrecognised for most of a century; the United States Golf Association publicly acknowledged him only in 1991. Saying Grant "invented the golf tee" is fair on the patent record. Saying his invention swept the game is not — the honest version is that he was first and Lowell was successful, and those are different achievements.

Why the flexible head is the actual claim. A rigid peg solves the height problem and creates a worse one. A clubhead at speed meeting a fixed post loses energy, twists off line, and takes damage. Grant's rubber head is a deliberate weak link in the direction of travel only: stiff enough vertically to support a ball, compliant enough horizontally to lie flat when struck. Steps 9 and 10 are the whole patent, and they take a minute. Modern plastic and wooden tees achieve the same thing differently, by being cheap and frangible enough to be knocked out of the ground and replaced without anyone caring.

What the sand tee tells you about the old game. A player carried a box of damp sand, knelt, and built a cone by hand before each drive — which is why early caddies carried a sand bucket, and why teeing grounds were placed near the previous green where the sand box was. When the peg arrived, that whole small ritual, and the equipment and course layout that supported it, disappeared within a generation.
