Fryderyk Chopin (1810-1849) lived for 39 years. John Keats (1795-1821) lived for 26 (actually 25) years. Both relied on family support in their emotional life, while living far away from their family homes, moving frequently, and surrounded by the ever-changing circle of friends, some unreliable, others faithful and caring.
Keats actually had tuberculosis that killed him at the age 25 in 1821; Chopin's lung disease was diagnosed as tuberculosis and that's what was on his death certificate but the illness is still being discussed, with cystic fibrosis being the next most favored candidate since this hypothesis was first put forward in the 1980s.
Chopin's health started to deteriorate in his teen years, and for the rest of his 39 years, he was under the care of a series of physicians. He suffered coughs, fevers, hemorrhages from the lungs (for over 20 years!), and other symptoms of lung disease. He was too weak to exercise, play sports, or even marry - his health was not strong enough to become a husband and support a wife with children.
Keats started getting persistent sore throats, fevers and coughing fits at a young age. He managed to go on a walking tour of Scotland that inspired his poetry, but later was often confined in bed. Like Chopin, he could not marry because of bad health and complete lack of resources. Towards the end of his life, he had to rely on the kindness of strangers to survive.
Alone, Dreaming of the Beloved
Here's an example, Keats writes to Browne:
July 8, 1819
My sweet Girl—Your Letter gave me more delight than any thing in the world but yourself could do; indeed I am almost astonished that any absent one should have that luxurious power over my senses which I feel. Even when I am not thinking of you I receive your influence and a tenderer nature stealing upon me. All my thoughts, my unhappiest days and nights have I find not at all cured me of my love of Beauty, but made it so intense that I am miserable that you are not with me: or rather breathe in that dull sort of patience that cannot be called Life.
I never knew before, what such a love as you have made me feel, was; I did not believe in it; my Fancy was afraid of it, lest it should burn me up. But if you will fully love me, though there may be some fire, ‘twill not be more than we can bear when moistened and bedewed with Pleasures.
You mention ‘horrid people’ and ask me whether it depend upon them whether I see you again. Do understand me, my love, in this. I have so much of you in my heart that I must turn Mentor when I see a chance of harm befalling you. I would never see any thing but Pleasure in your eyes, love on your lips, and Happiness in your steps. I would wish to see you among those amusements suitable to your inclinations and spirits; so that our loves might be a delight in the midst of Pleasures agreeable enough, rather than a resource from vexations and cares. But I doubt much, in case of the worst, whether I shall be philosopher enough to follow my own Lessons: if I saw my resolution give you a pain I could not.
Why may I not speak of your Beauty, since without that I could never have lov’d you? I cannot conceive any beginning of such love as I have for you but Beauty. There may be a sort of love for which, without the least sneer at it, I have the highest respect and can admire it in others: but it has not the richness, the bloom, the full form, the enchantment of love after my own heart. So let me speak of your Beauty, though to my own endangering; if you could be so cruel to me as to try elsewhere its Power.
You say you are afraid I shall think you do not love me—in saying this you make me ache the more to be near you. I am at the diligent use of my faculties here, I do not pass a day without sprawling some blank verse or tagging some rhymes; and here I must confess, that, (since I am on that subject,) I love you the more in that I believe you have liked me for my own sake and for nothing else. I have met with women whom I really think would like to be married to a Poem and to be given away by a Novel. I have seen your Comet, and only wish it was a sign that poor Rice would get well whose illness makes him rather a melancholy companion: and the more so as so to conquer his feelings and hide them from me, with a forc’d Pun.
I kiss’d your Writing over in the hope you had indulg’d me by leaving a trace of honey. What was your dream? Tell it me and I will tell you the interpretation threreof.
Ever yours, my love!
Chopin's package of letters from Wodzinska, with an inscription "my misery" (moja bieda) is found in his archives. Tied with a pink ribbon, it is a memorial to disappointment and loneliness of the sick composer.
In early spring 1837, his last letter from Maria Wodzinska, ended with:
‘Please accept my assurances of my feelings of gratitude, which I owe to You. Please be sure of the attachment which all our family cherishes for You, especially Your worst pupil and childhood friend. Adieu’."
Chopin died in Paris far from his family and loved ones (except sister Ludwika), in the company of friends and fellow artists, his letters were filled with nostalgia and longing for the family companionship. His death was a "public spectacle" of sorts, with musicians and well-wishers gathered around the death-bed of the genius. His gravest fear was to be buried alive, so to ensure that this grim possibility does not become real, he required an autopsy before burial.
John Keats died in Italy, far from his beloved Fanny Browne, and his brother George who emigrated to America; John was with his artist friends who took care of him in his last days. His younger brother, Tom, also died of tuberculosis, and John was misdiagnosed; instead of being properly treated for the incurable-then disease, he had his blood drawn and was served with mercury. He would have died of this treatment even without the TB!
Making pencil sketches of dying geniuses on their deathbeds was something of a 19th century hobby, here are the portraits of both Keats and Chopin:
Both artists had autopsy done after death. John Keats's autopsy after his death in Rome showed that his lungs were completely destroyed by TB, the cause of death was confirmed. Chopin's autopsy required by his last will, to ensure that he would not be buried alive, did not show the typical TB damage to lung tissue, hence the ongoing discussions about the cause of his life-long illness, most frequently identified with cystic fibrosis.
Plaster Casts - Face Masks
As it was customary, both Chopin and Keats had plaster casts of their faces made. Keats image dates back to 1816, when his friend, artist Benjamin Robert Haydon did a cast of life-mask.
In addition to the death mask made by Auguste Clésinger immediately after his demise on 17 October 1849 Chopin also had a cast of his hand made on his death bed.
John Keats has a lovely, simple monument in the Protestant Cemetery in Rome, among green trees, with a poetic epitaph for the "Young English Poet" - "Here Lies One whose Name was Written in Water."
