The Only Woman in the Room
Bradfield’s confidential secretary wrote the basis of the Sydney Harbour Bridge specification. Her career has a lot to teach technical professionals about influence, and about getting your work on the record.
On 24 March 1924, in the Minister’s room in Macquarie Street, the state of New South Wales signed the contract to build the Sydney Harbour Bridge. The price was £4,217,721/11s/10d. The Minister for Public Works, Richard Ball, signed it. John Bradfield, the chief engineer who had spent years arguing for the crossing, was beside him.
There’s a photograph of the signing. Most people who look at it look at the men in suits. Standing a little apart is a woman in her early thirties. Her name was Kathleen Butler, and she had more of that contract in her head than most of the men around the table.
Two months earlier she had been in the same room when the tenders were opened. “I was the only woman present in the Minister’s room when the tenders were opened,” she said later. “It was a most exciting moment.”
Her title was confidential secretary to the chief engineer. When I wrote No Second Attempt, I put it this way: that was the title and not the job.
The typist from Lithgow
Butler was born in Lithgow in 1891. She started work as a clerk and typist at the government testing office there and transferred to the Department of Public Works in 1910, aged nineteen.
In 1912 Bradfield was given his own branch for metropolitan railway construction. Butler was its first appointment. She was twenty-one and on £110 a year (equivalent to ~$16,000-18,000 today). Bradfield was on £1,000.
For the next decade she sat in his outer office and learned engineering the way most of us actually learned it: by being close to the work, handling the paper and paying attention. Nobody sent her on a course. By the time the Sydney Harbour Bridge Act passed in 1922, she was the first person appointed to the bridge team, and a Blue Mountains paper was already calling her the “God-Mother of the Bridge”.
What she actually did
The tender went out to the world in October 1922. From then until the contract was signed, nearly every word between the department and the bidders passed through her.
That meant six firms on three continents, twenty tenders and five different kinds of bridge. Clarifications went out on the department’s cable forms in clipped commercial language. What does the price include, and what does it exclude? Whose risk is the freight, and to which wharf? What does the firm mean by three years?
Butler answered what the file could already answer and put the rest in front of Bradfield. And every ruling given to one firm went to all six.
When the tenders came in, she worked with the engineers for six weeks, night and day, on the report that compared them. By the signing, a file that had started as a list of firms to write to had become two years and five months of paper.
Then there’s the sentence that matters most. In the preface to his 1924 doctoral thesis, Bradfield wrote:
“In preparing the Specification for the Sydney Harbour Bridge she was my only assistant; the technique of the Specification is hers.”
Read that as an engineer. The specification is the document that defines what the state is buying, how it will be tested and what the contractor can be held to. On the biggest public works job in the country, the chief engineer put in writing that its technique belonged to his secretary.
London, 1924
The design wasn’t drawn in Sydney. Dorman Long won the contract, and the detailed design was drawn in London by a department working under the consulting engineer Ralph Freeman. The state kept two rights: to approve the drawings and to witness the steel being tested. Both rights could only be used where the work was, and the work was twelve thousand miles away.
A cable got an answer in hours. A question sent by mail took two months to come back.
So in the last week of April 1924, Butler sailed for London on the Ormonde with three of the department’s engineers. The Australasian reported: “Miss Butler is in charge of the visiting party, on £500 a year.” That was almost five times her starting salary, and a remarkable figure for a woman in the public service of the day.
She set up the London office, worked alongside the designers and visited Dorman Long’s works in Middlesbrough. When she sailed from Southampton on the Berengaria on 15 November, the office was open and staffed, the registers were running, and the London end of the job would carry on without her until the bridge was finished.
What a mid-career engineer can take from this
I’ve spent fifty years in and around engineering organisations. I’ve met a Kathleen Butler many times, under other names, in other offices. Here’s what her story teaches.
1. Whoever holds the record holds the project
Butler had no authority over anyone outside her own office. She had something more durable. She was the project’s memory. Every question, every answer and every ruling went through her. When anyone needed to know what had been agreed, they came to her.
The modern versions are the Request for Information register, the decision log, the change register and the correspondence file. These jobs usually go to whoever is most junior or slowest to say no. Take one on deliberately and run it well. Within a year you’ll be the person who knows what was decided and why, and that’s a kind of influence no organisation chart gives you.
2. Fairness is a process, not a feeling
Answer one bidder, answer all six. It’s a simple rule, and it’s tedious to apply for fifteen months across three continents. It’s also what protected the state. No losing firm could say it had been told less than the winner, and Bradfield’s recommendation was hard to attack because the process behind it was clean.
The same applies in every procurement, design review and assessment panel you’ll ever sit on. Decide your rules before the pressure arrives and write them down. Then apply them when it’s inconvenient, because that’s where reputations are made.
3. Doing the job without the title leaves you exposed
For fifteen years Butler did work we’d now call technical lead or project manager. Her title said ‘secretary’.
When she married in 1927, the public service marriage bar required her to resign! A better title wouldn’t have saved her, because the rule applied to every married woman whatever her job. But the title shaped how she was remembered. For most of the next century she was “Bradfield’s secretary”, if she was remembered at all.
If you’re working above your grade, get it on paper. Put it in your position description, write your scope into the project charter and put your name on the deliverables you produce. That isn’t vanity. The record is what’s left when you leave the room.
4. Somebody has to write it down
Almost everything we know about what Butler did comes from a handful of sources, and the most important is a few sentences in Bradfield’s thesis preface. Without them she’d be a face at the edge of a photograph.
If you lead people, give credit in writing, by name and specifically. “Thanks to the team” erases people. “The technique of the specification is hers” makes them permanent.
If you don’t lead people, keep your own record of what you did, when you did it and what came of it. Nobody else will do it for you.
The view from Kurraba Point
Butler married Maurice Hagarty, a grazier from Cunnamulla, in April 1927 and left the department. For three decades she all but disappeared from public life.
In 1961 she bought a house at Kurraba Point on the north shore. It was a house from which the Bridge can be seen. She lived there until she died in July 1972, aged eighty-one.
Recognition came late. In 2019 Sydney Metro named one of its tunnel boring machines Kathleen. In 2024 a blue plaque went up in her honour.
She spent the last eleven years of her life looking across the water at a structure whose specification was hers. I’d like to think she knew exactly what she was looking at.
Kathleen Butler appears in the early chapters of my new book, No Second Attempt: The Men Who Built the Sydney Harbour Bridge Out Over Open Water and Closed It in a Single Night, 1923 to 1932. She runs the tender correspondence and sails to London to watch the design take shape in somebody else’s office. The book covers the full build, from Bradfield’s drawing office to the granite quarry at Moruya to the night the two halves of the arch finally met. I’m a civil engineer, and I went back to the record to tell it the way it actually happened.
