Thomas Wentworth Higginson called him "the best and most sympathetic literary counselor I ever had." Harriet Beecher Stowe noted that "he did habitually and quietly more good to everybody he had to do with than common." Oliver Wendell Holmes wrote that, "Very rarely, if ever, has a publisher enjoyed the confidence and friendship of so wide and various a circle of authors." Critic Edwin Percy Whipple told of how Fields was fond of teasing his friends but never to the point of offending them. "His wildest freaks of satire never inflicted a wound," he wrote, and "when he laughed at the expense of one of his companions, the laugh was always heartily enjoyed and participated in by the object of his mirth."
In addition to letters, there were many poetic tributes, including "Auf Wiedersehen" by Henry Wadsworth Longfellow and "In Memory" by John Greenleaf Whittier. One of the most touching came from the minor writer Parke Godwin, mostly known as a journalist. He wrote to Mrs. Fields in particular:
I cannot wish thee comfort in this hour
Of life's supremest sorrow; for I know,
By aching memories, how little power
The best words have to mitigate a woe,
With which, in its own bitterness alone,
The heart, amid the silences, must deal.
But here, where ocean makes eternal moan,
Along its melancholy shores, I feel
How mightier than nature's loudest voice
Is that soft word, which to the ruler said,
Amidst his desolated home, 'Rejoice!
Thy dear one sleepeth: think not he is dead:'
All death is birth, from out a turbid night,
Into the glories of transcendent light.
The year before her husband's death, Mrs. Fields opened their home to Sarah Orne Jewett for part of the winter and their vacation home for part of the summer, establishing a life-long "friendship." About a year after Mr. Fields's death, Jewett and the widow Fields moved in together. Their "Boston marriage" seemed very public, and was not criticized; it is unclear how close their relationship was.
