Margaret Crane

She invented the first home pregnancy test and got paid $0 for it.

In 1967, Margaret Crane was a 26-year-old graphic designer hired to work on a cosmetics line at Organon Pharmaceuticals.

One day, she took a tour of the lab and saw rows of test tubes sitting above mirrors.

Those were pregnancy tests.

Doctors would send women’s urine samples to the lab, and after mixing in reagents, a red ring would appear at the bottom of the tube if the woman was pregnant.

The whole process took up to two weeks.

And Margaret thought: “This is so simple. A woman should be able to do this herself.”

So she went home to her New York apartment, sat at her kitchen table, and started prototyping.

A plastic paperclip box caught her eye.

She cut a strip of Mylar (a reflective film) and glued it to the bottom.

She dropped in a test tube.

A pipette to add the urine.

If the red ring appeared, it would reflect clearly in the mirror below.

That was it.

A pregnancy test a woman could do alone.

She called it “Predictor.”

Organon wasn’t impressed.

Executives rejected her idea immediately.

They were afraid of losing business from doctors.

Afraid women would “panic” if they saw the result.

Afraid women would seek abortions.

Still, Organon quietly filed a patent in her name in 1969.

And when the idea reached Organon’s parent company in the Netherlands, they approved a small test market, outside the U.S.

Crane wasn’t invited to the internal meeting where prototypes were being presented.

She wasn’t even told it was happening.

But she heard the rumors.

So she showed up.

The male designers had filled their prototypes with pink trim, flowers, plastic gems... even pom-poms.

Crane’s design? Minimal. Clean. Unbranded. Serious.

Ira Sturtevant, the ad exec brought in to lead marketing, immediately picked hers.

The test launched first in Canada in 1971.

Where birth control had been legal since 1960 and abortion since 1969.

It sold for $5.50 and was advertised in Quebec’s Châtelaine magazine: Discover if it’s YES or NO. Quickly. At home. In private.

The U.S. was slower to catch up.

FDA approval didn’t come until 1976.

The Predictor finally launched in the U.S. in 1977. Ten years after Margaret built her first prototype.

By then, three pharmaceutical giants had licensed the product from Organon.

Crane’s name was on the patents.

But in corporate environments like Organon, anything you invent on the job typically belongs to the company.

She did sign away her rights for $1.

But she never received the $1.

For decades, her contribution was erased.

Then in 2012, the New York Times ran a short feature on the history of pregnancy tests.

They didn’t mention her name.

She was reading the paper at breakfast.

And she knew she had to speak up.

She contacted the journalist and finally told her story.

Today, over 80% of women confirm pregnancies using at-home tests.
