M 0 NIX, Sworn In For The Defendant, 69th To Testify

M. O. Nix, witness for the Defendant in rebuttal, at the Trial of Leo Frank in the Fulton County Superior Court of Atlanta, Georgia, in 1913 (Testimony Portion From July 28 - August 21, 1913; Closing Arguments August 21-25, 1913)
M. O. Nix, credit manager and bookkeeper for Montag Bros., oversaw all National Pencil Company documents. He positively identified Leo Frank’s handwriting on:

Weekly financial sheets (May 22, 1912 – May 24, 1913; Defendant’s Exhibit 9)
House orders 7187–7197 (pages 56–57; Defendant’s Exhibit 12)
11 requisition sheets (Exhibits 25–35)

Nix hired stenographer Hattie Hall and raised her pay August 1—Frank and Montag uninvolved.
April 26 morning at Montag Bros.:

Frank arrived piled with work; his stenographer was absent.
He asked Nix to lend Hall to the factory.
Nix refused until Montag’s mail was done, then allowed Hall to assist Frank that morning—not afternoon.

On cross-examination, Nix admitted:

He never saw Frank write the documents—only recognized his figures, abbreviations, payrolls.
State’s Exhibit K (letter) “looks like Frank” but “entirely different” from usual numeric shorthand.
Capital letters alone give no fair comparison.

On re-direct, Nix clarified he only knew Frank’s business scrawl—not formal letters.
Nix’s ledger-proof testimony:

Authenticated every financial sheet Frank claimed to finish Saturday.
Placed Frank at Montag Bros. morning—begging for help, not hiding.
Demolished State’s “forged documents” with seven years of bookkeeping.

The prosecution’s “Frank can’t write” smear collapsed under a mountain of verified numbers.
