Some time ago, Tessa Hadley suggested that we explore one of Eudora Welty’s female alliances. When blog reader Elizabeth Ahlstrom also wrote to us to mention Katherine Anne Porter’s mentorship of Welty – a fellow writer from the Deep South – we were further intrigued.

This literary bond particularly piqued our interest since we have long felt indebted to the authors who took us under their wings when we were starting out. And, more recently, we thanked our lucky stars when Margaret Atwood generously agreed to write the foreword to A Secret Sisterhood: The hidden friendships of Austen, Brontë, Eliot and Woolf.

Katherine Anne Porter’s lifestyle, roaming from place to place and lover to lover, bore little resemblance to that of Eudora Welty, who returned to her family home in her early twenties and remained there unmarried until her dying day.

But, a few years later in the late 1930s, when the middle-aged Porter came across Welty’s short stories in the Southern Review, she knew she had found a kindred spirit in the twenty-eight-year-old.

The two women shared a deep admiration for the work of Jane Austen, Virginia Woolf and Katherine Mansfield, and, as Southern writers, they considered themselves ‘bathers in the same sea’. Here, felt Porter, was a talent to nurture.

Welty never forgot the helping hand she received from the more established writer, looking back with wonder at her first letter from Porter, which seemed to come ‘out of the clear blue sky’. Porter invited the younger woman to visit her in the two-room apartment she shared with her third husband in Baton Rouge, Louisiana – 150 miles south of Jackson, Mississippi, where Welty lived with her mother in their large mock Tudor home.

It took Welty six months to gather the courage to take Porter up on the invitation. She twice got halfway there before turning back. But, one midsummer day in 1938, mutual friends drove her down to Porter’s home, where she enjoyed a convivial evening, the open windows letting in a welcome breeze as she listened intently to the conversation.

True to her word, Porter went out of her way for the modest, young writer, nominating her for a Houghton Mifflin Harcourt award, introducing her work to Ford Madox Ford, and inviting Welty to accompany her to Yaddo – a prestigious artists’ colony in Saratoga Springs, Upstate New York.

At Yaddo it became clear that the outwardly shy Welty shared with her glamorous mentor a love of socialising and a knack for friendship. Neither woman got much work done during their two months together because they could not resist the temptations of companionship: Welty tried to teach Porter to drive and they made excursions to view the renovations at the nearby colonial home that the recently-divorced Porter had just purchased.

That summer, Porter did begin work on a foreword to Welty’s first collection of short stories, A Curtain of Green – an act that Porter herself predicted would add $10,000 to the book’s sales. But the gesture was not without its complications. Porter, who had always struggled with deadlines, failed to turn it around on time. Welty chose to postpone the publication date rather than chivvy on her mentor, and the book did eventually come out complete with Porter’s promised foreword.

Their bond would always combine the literary and the social. One of Welty’s abiding memories of Porter was an evening they spent together in the late 1970s. By this stage, both women had been awarded Pulitzer Prizes and Porter would soon honour her protegée by presenting her with a gold medal from the National Institute of Arts and Letters – an occasion for which Porter had prepared months in advance with the purchase of an Italian silk pant suit.

Despite recovering from cataract operations and suffering with a broken hip, the eighty-four-year-old spent all morning cooking for her friend. The pair began with spears of asparagus, butter melting onto their fingers, followed by ‘dainty catfish fingerlings’, which they ate using golden cutlery. They finished up with strawberries and champagne, celebrating and chatting all afternoon.

When Porter died at the age of ninety, Welty took a group of friends out for a crab supper after the memorial service so that they could reminisce in a style that would capture Porter’s spirit. And Welty looked back on her bond with Porter more publicly too. She wrote a tender essay about it for the Georgia Review, and her introduction to the Norton Book of Friendship conjures up the way friends give tribute to one of their group who has passed away: ‘As if by words expressed they might turn friendship into magic, the magic that now, so clearly, it had been.’

An Invitation to our Female Literary Friendship Event at the British Library, July 11 2017, 7.15-8.30pm:

We are honoured to be sharing a stage with novelist Kate Mosse, the founder of the Women’s Prize for Fiction, and her friend, the biographer Rachel Holmes. We will be talking about the friendships that we have explored in A Secret Sisterhood and they will be sharing details of their own literary friendship.

If you are free, we would love to share the occasion with you too.
