Martin Lampe, the Old Soldier Who Woke Immanuel Kant

Immanuel Kant made sure he woke at five in the morning by employing a retired soldier, Martin Lampe, to come into his bedroom shortly before the hour and not leave until the philosopher was awake. Manfred Kuehn’s 2001 biography says Lampe was “under orders to be persistent,” and the best surviving account of the scene comes from Kant’s friend and executor Ehregott Wasianski, as retold in English by Thomas De Quincey.

That is the short answer. The longer one is more interesting, because the people who tell the story most often tend to improve it.

The scene as De Quincey gives it

De Quincey published “The Last Days of Immanuel Kant” in 1827, working from Wasianski’s memoir of 1804. In it, the morning goes like this: “Precisely at five minutes before five o’clock, winter or summer, Lampe, Kant’s servant, who had formerly served in the army, marched into his master’s room with the air of a sentinel on duty, and cried aloud in a military tone,—‘Mr. Professor, the time is come.’”

Then comes the sentence that people paraphrase into legend. Kant “invariably obeyed without one moment’s delay, as a soldier does the word of command,” and never allowed himself “a respite, not even under the rare accident of having passed a sleepless night.” As the clock struck five, De Quincey says, Kant was already seated at the breakfast table with his tea.

Notice what is on the page and what is not. A man in the doorway, a sentence of five words, a philosopher who complies. Nothing about a struggle. De Quincey’s Kant gets up like a soldier, because a soldier is the one telling him to.

What the bedroom was like

The same account describes the bed Lampe was dragging him out of, and it is worth a look. Kant slept on a mattress, wrapped in a quilt: cotton in summer, wool in autumn, both at the start of winter, and for hard cold an eider-down padded with wool over the shoulders. He had a practiced routine for getting in. He sat on the edge of the bed, vaulted “obliquely into his lair,” tucked one corner of the covers under his left shoulder, passed it round his back, and did the same with the other, until he was “swathed like a mummy.” De Quincey says he used to tease him that he was like a silkworm in its cocoon.

The room was unheated even in the worst winters, at least until his final years, when his friends talked him into a very small fire. It was kept dark day and night, summer and winter, and if he needed to leave it in the dark he followed a rope tied to the bedpost and run into the next room.

Put those details next to the five o’clock summons. A cold, black room, a body wound into a warm cocoon, a man whom De Quincey says fell asleep “generally immediately,” and then at 4:55 a stranger in boots with a loud voice. The arrangement works against the sleeper on purpose. The darkness removes any hint that morning has come, the cocoon makes leaving it a decision, and Lampe is the reason the decision is not left to the sleeper.

What Kuehn adds

Kuehn, a philosopher who spent years on Kant’s life, gives the same routine in plainer language. In his account Kant “got up at 5:00 A.M. His servant Martin Lampe, who worked for him from at least 1762 until 1802, would wake him. The old soldier was under orders to be persistent, so that Kant would not sleep longer.”

Two sentences later comes the part I like best: “Kant was proud that he never got up even half an hour late, even though he found it hard to get up early. It appears that during his earlier years, he did sleep in at times.”

That changes the picture. The famous regularity was not a temperament that came with the man. It was built, over some years, and one of the parts was a paid person whose job was to refuse to take no for an answer. Elsewhere Kuehn lists what Lampe handled: clean clothes, the errands, the supplies, and making sure Kant “woke up on time.” Waking was one item in a household’s worth of logistics, not a ceremony.

This is where the idea of precommitment, as old as Ulysses and the ship’s mast, does real work. Ulysses did not trust his future self near the Sirens, so he gave his crew the instruction while his head was clear and told them to disregard what he said later. The Kant of the evening, sensible and rested, did something similar for the Kant of 4:55 a.m. Whatever case the half-asleep Kant made for ten more minutes, the one person who heard it was paid to keep going. Kuehn’s word “persistent” fits that reading, though Kuehn does not use the word precommitment.

The version where Kant begs

Search for this story now and you will find a livelier version: Kant pleaded, bargained, offered Lampe money, and Lampe, under strict orders, refused. I looked for it in the places it should be.

It is not in De Quincey’s text, which I downloaded from Project Gutenberg and searched for every mention of Lampe. It is not in the passage from Kuehn’s biography, which I read in a scanned copy on the Internet Archive. A Cambridge University Press introduction to Kant’s lectures, which I saw only in a search summary, reportedly says Lampe shouted “It is time!” and that Kant bragged to guests that Lampe never had to wake him twice. I could not open that page, so I am not relying on it.

What the sources I did read support is narrower. There were orders. The orders were about persistence. Kant found early rising hard. He was proud of keeping to it. And, in the phrase Wasianski’s account uses, he did not take a day off even after a sleepless night. The pleading is a reasonable guess about how a man behaves in a dark room at five, and it may well be in one of the other 1804 memoirs. De Quincey’s preface names Jachmann and Borowski among his sources, and Kuehn cites both in his notes, but I found no passage in either that I could tie to the morning call. If someone can point me to one, I would like to see it.

I should also say that nobody I read quotes Kant’s actual instruction to Lampe. “Under orders” is a biographer’s summary of an arrangement, and I could not see the note that supports it.

A small discrepancy

The two accounts differ by five minutes. Kuehn has Kant up at five. De Quincey has Lampe marching in at five to five and Kant at the table when the clock strikes. These agree if you allow a man five minutes to get into his clothes, which is how I read it. Still, it shows that even this famously exact routine reaches us as a rounded number in one place and a sharper one in another.

The sharper one has a nice effect. Lampe’s job was not to wake Kant at five. It was to wake him early enough that Kant would be seated by five, with the working day starting at the stroke. The servant was keeping the schedule of a clock he could not see, in a city where, as Heinrich Heine put it in a passage Kuehn quotes, the neighbours knew it was 3:30 when Kant stepped out with his grey coat and cane, and “the old Lampe, anxious and worried,” walked behind him with an umbrella “like an image of destiny.” Kuehn calls that portrait “a caricature of a caricature,” so the umbrella is better taken as atmosphere than as evidence.

How it ended

The arrangement lasted about forty years and ended badly. According to De Quincey’s Wasianski, Lampe had been “dull and stupid” but tolerably faithful early on, and then, “presuming upon his own indispensableness,” grew careless, and in De Quincey’s phrase became “an old ruffian” who was “apt to fall from intoxication.” Kuehn, drawing on the same events, says he became quarrelsome, did not do his job, was frequently drunk, and exhibited a certain “brutality.” In January 1802, Kant told Wasianski that Lampe had done him a wrong he was ashamed to repeat. Wasianski arranged a replacement, a man named Kaufmann, and Lampe was out by the end of the month.

What happened next is the oddest detail in the whole story. Kant kept calling the new servant “Lampe.” To correct himself he wrote in his notebook. De Quincey translates the entry as “Mem.: February, 1802, the name of Lampe must now be remembered no more.” Kuehn renders it “the name Lampe must now be completely forgotten.” The wording differs between translators, but the note, and the habit it was fighting, are in both.

De Quincey reads it as a man missing the voice and the “old familiar face” of forty years. Kuehn calls it a “performative contradiction,” a note about forgetting that proves a man cannot. Neither claims to know what Kant felt, and neither should be pushed too far. The plain facts are enough: for four decades the first voice Kant heard each morning was Lampe’s, and when it stopped he could not stop reaching for the name.

What the story is good for

Kant’s five o’clock rise tends to show up in lists of famous early risers, as one of a dozen exhibits for the idea that greatness starts before dawn. I have written about what those lists leave out in a look at seven historical morning schedules. Lampe is one more thing the list leaves out. The person who got Kant up was on the payroll.

This puts him in an old tradition. Industrial Britain had paid knocker-ups who tapped windows with poles until someone lit a candle, and Kant’s version was the same service moved indoors, with a salary, a soldier’s habits and a master who had asked for it himself. It is also a useful contrast with another famous would-be early riser. Samuel Johnson wrote the same resolution to rise early in his private diary for decades and kept breaking it; Kant, a generation later in Königsberg, simply handed the problem to someone else, and kept his word to himself by keeping a paid witness on call.

I think the quiet lesson is about the evening, not the morning. Nothing in De Quincey or Kuehn suggests that Kant was stronger at five a.m. than anyone else. What they show is a man who, when rested and sensible, set things up so that the unrested, unreasonable version of himself did not get a say. Lampe’s volume mattered less than the fact that someone with no stake in Kant’s comfort was standing in the doorway.

Quick questions people ask

How much sleep did Kant get? Roughly seven hours, by my arithmetic rather than anyone’s statement. De Quincey’s version of Wasianski says Kant studied until nearly ten, spent his last quarter hour on undemanding thoughts so as not to excite himself, and then fell asleep, usually at once. Count from ten to the five o’clock tea and the total is about seven. None of the accounts I read gives a measured figure.

What happened to Lampe after Kant dismissed him? He was pensioned. De Quincey calls it a handsome pension for life, and Kuehn adds that it was a yearly sum on the condition that neither Lampe nor his relatives ever bothered Kant again. De Quincey also reports that Kant drafted a codicil to his will beginning with a complaint about Lampe’s ill behavior, then cancelled the passage so that no trace of his anger remained. Kuehn’s biographical glossary dates Lampe 1734 to 1806, so he outlived his master by about two years.

Did Lampe live in Kant’s house? The sources I read do not settle it. Kuehn says Lampe had his own quarters, married without asking Kant, and thereby cost Kant extra support money, since Lampe now needed more. Whether those quarters were under Kant’s roof, and how that changed in Kant’s last frail years, I could not establish from the pages I had.

Where can I read the Wasianski account myself? De Quincey’s essay is in volume 2 of his Narrative and Miscellaneous Papers, free on Project Gutenberg as ebook 6147. Its own heading says it is drawn from the German of Wasianski, Jachmann, Borowski and others, so it is an adaptation, not a line-by-line translation, and the quotations in this article are De Quincey’s English, not Wasianski’s German. Wasianski’s own memoir appeared in 1804.
