Exhibit No. 03 — The Ledger

A life ruled in ink, 1879 — Present

Every entry below is drawn from the workshop books and the field journal. The archive presents them in the order Black himself kept: plainly, and without ornament.

1879

A machinist's son

Matthew Black is born in Dayton, Ohio, third son of a locomotive machinist. By twelve he can bore a cylinder true to the thousandth.

1896

The bicycle trade

Black apprentices at a bicycle works on West Third Street, two doors from the Wright Cycle Company. He and Wilbur Wright first argue — then agree — about the problem of balance.

1899

The glider

Black joins the workshop in Dayton, sketching airfoil curves with Orville. The first glider is designed on a shared set of boards.

1900

First season at Kitty Hawk

Black travels with the crates to North Carolina. He records sixty-two tethered flights and coins the workshop rule: "The sand does not lie."

1901

The failed glider

Tests at the sand dunes disappoint. Black's notes record a stalling pitch that no one can yet explain. The brothers nearly abandon the work; Black talks them back to the tables.

1902

The wind tunnel

A small wind tunnel is built from a starch box and a fan wheel. Black measures lift across eighty wing sections, correcting the brothers' data and the published tables alike.

1903

The engine

No manufacturer will build a motor light enough. Black machines the crankcase from a single block of aluminum in six weeks. Finished weight: 183 pounds.

1903

The first flight

On 17 December, four flights from the rail at Kill Devil Hills — the longest 852 feet in 59 seconds. Black's hand wrote the final entries on the launch rail.

1908

The return

After the Fort Myer crash, Black returns to Dayton to refit the demonstration machine and opens a small pattern shop of his own on Third Street.

1916

The last commission

Black builds wind gauges for the Army Signal Corps, then quietly retires from aviation. He tells a reporter: "I was present at the one that mattered."

1961

The archive

Black formally deeds his field journal, tools, and corner-mounted photographs to the newly founded Wright Archive, serving as its first honorary archivist. He remains a familiar presence in the reading room.
