‘I Took Out A Hair. I Taped It To The Card.’ Ronan Prynne-Machado, 84.

SUITLAND, Maryland — The hair is still on the card.

It is taped across the corner of job card 71-0412 with a strip of linen tape gone the colour of weak tea, under four words in pencil: out of gate, mine.

Ronan Prynne-Machado put it there in the spring of 1971 and never took it off. He died of a stroke on 11 July, at 84, at his home in Suitland, Maryland.

The trade

He retouched prints at a federal photographic laboratory from 1964 to 1995. The work was neither secret nor clever. A briefing print had to be legible across a conference room at three metres, often at an angle, often to a man who would not put his glasses on.

So the retoucher dodged and burned to hold the tones, laid dye with a 000 sable to knock back a hot highlight, drew a 6H graphite line where an edge had gone soft, and used opaque white — the last resort, and the one that shows — on dust, fibres and scratches in the emulsion.

Eleven people did that job in that building. Every one of them signed the card.

The book

In 1988 a book called The Retouched Century named him. Not as one of a class of technicians: by name, on page 211, in three sentences, as the man who removed objects from three famous photographs.

He wrote to its author three times. He wrote to eleven publishers over thirty years — thirty-one letters, nineteen replies — and kept the whole correspondence in a manila folder his granddaughter found in a footlocker, marked ANSWERED in the same pencil as the job card.

The letters barely vary. Each sets out the three job numbers in order, and twenty-eight of the thirty-one end on the same two lines: I took out a hair. I taped it to the card. Then his name, and the job number again underneath it.

This newspaper has taken its headline from those two lines, which is a thing he did not agree to and cannot now be asked about.

The log

He also took home something he had no right to take: a carbon duplicate of the laboratory's retouch log.

14,203 entries. Date, job number, what came off, what it was done with, initials. He began copying it in 1966 and stopped in 1995, and he told his granddaughter once, in a sentence she wrote down at the time, that he did it because one day somebody was going to say he had.

We asked the government for its own copy, expecting nothing. The release covers 1979 to 1995; everything earlier went on a records schedule in 1997. Of 340 entries we could set side by side, 338 match to the word. One has a transposed date. One appears in his carbon and not in the official copy at all, and both pages are published with this story.

The nearest thing in our own vault is PX-1963: twelve tests applied to a set of papers by people who had the papers in front of them. Nobody did the equivalent here in thirty-eight years.

The three photographs

Job 69-1140: fibre, copy glass, opaque wh., 2 strokes.

Job 71-0412: hair, gate, dye 4B + graphite. That is the hair on the card.

Job 63-2288: reg. cross, camera, opaqued at request of briefing officer.

The third is the one worth explaining. Every frame from that camera carried a fiducial cross exposed onto it by a plate behind the lens — a surveying mark, printed by the machine, on every negative it ever made. On 63-2288 the cross falls across the object everyone argues about. The briefing officer asked for it out so the shape could be read at three metres.

What the 1988 book describes as an object removed from a photograph is the ghost of the laboratory's own registration mark, taken off at a named man's request, on a Tuesday, and written down.

The hair

We sent the card to a forensic microscopist who was not told what the story was.

Dr. Halvard Onyekwere-Sant reports a human head hair, 84 micrometres at the shaft, medium brown, consistent in scale pattern and pigment distribution with samples his family took from a brush in his bathroom. He declines the word identification, and so do we.

What was corrected

Two publishers corrected in later editions, in 1996 and in 2004. Neither correction uses his name, which is the name the original sentence used.

What this desk takes from it

Retouching was a documented trade. It had a vocabulary, a fee schedule, a signature line and a log, and for the whole length of the argument the log sat in a building with a switchboard and a number in the directory.

Merrit Vaughan-Sloane, who wrote the book and answers us at the foot of the page, makes the objection we cannot close: the log records what came off prints that were made, and it cannot record a negative nobody printed. That is true. It is the part of this story that stays open, and he is right that the third job card is a record of somebody deciding what a room would be able to see.

He did not label the folder VINDICATED. He labelled it ANSWERED, which is a smaller claim, and it is the one he was entitled to.

It is in Hyattsville now, with his granddaughter, along with the card, the tape, and the hair.
