In 1879, illustrator Emily Gertrude Thomson appointed to meet Lewis Carroll at the South Kensington Museum. She had arrived at the rendezvous before she realized that neither of them knew what the other looked like.

“The room was fairly full of all sorts and conditions, as usual,” she wrote later, “and I glanced at each masculine figure in turn, only to reject it as a possibility of the one I sought.”

As the clock struck, she heard high voices and children’s laughter ringing down the corridor, and a tall, slim gentleman entered holding two little girls by the hand. “He stood for a moment, head erect, glancing swiftly over the room, then, bending down, whispered something to one of the children; she, after a moment’s pause, pointed straight at me.”

He dropped their hands, came forward with a smile, and said, “I am Mr. Dodgson; I was to meet you, I think?” She smiled and asked how he had recognized her.

“My little friend found you,” he said. “I told her I had come to meet a young lady who knew fairies, and she fixed on you at once.”
