It goes against masculine pride to have a wife helping support the household, and once a man’s pride is shattered, anything can happen to him. …

There was a couple I once knew in Chicago. At the time of their marriage the husband was earning $5,000 a year. Two years after marriage the wife went to work, and presently was making more than her husband. His home became a desolate place, for his wife’s job required her to travel to other cities. Driven to seek companionship to escape from the loneliness of home the man became addicted to drink. Today they are divorced. The woman is a notable business woman, and the man is a drunken drifter.

But, the women will comment, the husband drank. What of it? No husband drinks to excess unless there’s a reason for it. If the truth were known there are many men who began drinking because their wives took to work.

— William Johnston, These Women, 1925

During the Jim Crow era, it was difficult and dangerous for African-Americans to travel — they were routinely refused even basic amenities such as food and lodging. Civil rights leader (and now Georgia congressman) John Lewis remembered a family trip in 1951:

There would be no restaurant for us to stop at until we were well out of the South, so we took our restaurant right in the car with us. … Stopping for gas and to use the bathroom took careful planning. Uncle Otis had made this trip before, and he knew which places along the way offered ‘colored’ bathrooms and which were better just to pass on by. Our map was marked and our route was planned that way, by the distances between service stations where it would be safe for us to stop.

Accordingly New York mail carrier Victor H. Green began to publish The Negro Motorist Green Book, a guide “to give the Negro traveler information that will keep him from running into difficulties, embarrassments and to make his trip more enjoyable.” Green paid his readers to contribute reports of road conditions, sites of interest, and information about their travel experiences. Julian Bond later recalled:

You think about the things that most travelers take for granted, or most people today take for granted. If I go to New York City and want a hair cut, it’s pretty easy for me to find a place where that can happen, but it wasn’t easy then. White barbers would not cut black peoples’ hair. White beauty parlors would not take black women as customers — hotels and so on, down the line. You needed the Green Book to tell you where you can go without having doors slammed in your face.

The book was published annually nationwide from 1937 to 1964. The New York Public Library has the full collection.

08/25/2017 UPDATE: Using structured data extracted from the books’ listings, NYPL Labs’ Brian Foo created Navigating the Green Book, an interface that lets you map a trip between two points based on either the 1947 or the 1956 edition. The program looks for a restaurant every 250 miles and lodging every 750 miles. (Thanks, Sara.)

When Triberg, Germany, unveiled a new parking garage in 2012, it included 12 parking spaces designated for women’s use, as has been required by German law since the 1990s. The spaces are somewhat larger than normal and located near the mall entrance, to reduce the possibility of sexual assault.

Due to the Triberg mall’s shape, it also has one space on each level that requires a complex parking maneuver. Mayor Gallus Strobel decided to designate these for men … which brought on a backlash from people who felt that it insults women’s parking skills.

“It’s a joke,” Strobel told ABC. “Everyone in Triberg thinks it is a joke. We looked at the two parking spaces and we said, ‘They could be dangerous for your car,’ so at the same time, we decided to make them for men, and then give 12 others for women.”

Is this sexist? Considerate? Unnecessary? Germany isn’t the only nation that uses women’s parking spaces — they’ve also been introduced in Austria, Switzerland, and China, where the spokesman for one northern mall told AFP, “The fact that our women’s parking spaces are wider is simply due to practical reasons and shouldn’t imply that women are worse at driving than men.”

For his part, Strobel seems to have his eye on the bottom line — after Triberg controversy made the news, the town’s tourist traffic increased from 250,000 to 400,000. “Women can come here and prove me wrong,” he told the Times of India, “and while they’re at it, they can see the town’s attractions.”
