My father held diametrically opposite views, but as both were believers in the utmost freedom of speech, the social clash of arms never engendered a moment’s ill feeling. They were closely united upon the questions of anti-slavery and woman’s rights, and they were drawn by a common impulse to progressive and philanthropic movements. Karl Heinzen, who with his wife and son made a part of the Doctor’s household, was a striking and remarkable figure. He was a man of massive intellect, possessing a high reputation in Germany as a writer of both prose and verse. His intense love of liberty and hatred of shams had made him an exile in America in the tumultuous years preceding the Civil War. He was of noble stature and frame, a spacious temple for a great soul, his rugged face betraying his indomitable and fearless character. Boston never realized the value or distinction of this moral hero, for the reason that the English language was more formidable to him than despots and monarchies. But in Dr. Zakrzewska he had a friend who appreciated his noble talents and virtues. ... I have dwelt upon this conjunction of the Doctor with Karl Heinzen because his influence upon her life was deep and abiding. To see him working about the ample grounds, trimming the grapevines and attending to the fruit trees--his recreation and pleasure--and, when the weather permitted, to behold the afternoon table-gathering under the leafy shade at the back of the grounds which rose above the house, was to receive the impression of a bit of the Fatherland--a German grafting on a Yankee hillside. The glimpse was often through or over the board fence which separated my own house on the hilltop when, in 1868, I became the Doctor’s closely adjacent neighbor. What animated talk enlivened the coffee, and how many friends enjoyed first and last the retirement and refreshment! In the early days, sweet Mrs. Severance and her interesting family lived also on Cedar Street; the Prangs were near at hand on Center Street; the Koehlers and the Elsons were in the vicinity. The beautiful suburb of Roxbury was then full of natural charm, an object of interest to strangers visiting Boston and at that date untouched and unspoiled. I remember a traveled friend pointing down Cedar Street towards the Doctor’s house and asking, “Have you ever been to Versailles?” adding, “The arches of these glorious elms are a reminder of it.” For many years Dr. Zakrzewska had a summer cottage at York Harbor but it is of her busy city homes that her friends wrote most often. One of the former internes writes to her in later days: The year spent by me in the Hospital will always be remembered with great pleasure, particularly that part of it when I was quarantined at the Maternity and you used to ask me down to dinner at your house nearly every evening.
