Henrik Dam's Birth Card: The 4 of Diamonds

In the record

Carl Peter Henrik Dam (21 February 1895 – 17 April 1976) was a Danish biochemist and physiologist. The birth-card coordinate for February 21 is the 4 of Diamonds — a calendar position, not a forecast of the 1943 Physiology or Medicine prize.

The 4 of Diamonds coordinate

Henrik Dam's birthday maps to the 4 of Diamonds (The Financial Foundation Builder). Card Blueprints treats that as a 365-day coordinate: solar value = 55 − (2 × month + day), and the year is unused. It is not a prediction about a Nobel Prize and not a verdict on Henrik Dam. The card's own language, quoted as system copy rather than biography: You build a floor that lasts and still let money move when the work requires it.

Henrik Dam in the public record

He was awarded the Nobel Prize in Medicine in 1943 for joint work with Edward Doisy in discovering vitamin K and its role in human physiology. Dam's key experiment involved feeding a cholesterol-free diet to chickens. He initially replicated experiments reported by scientists at the Ontario Agricultural College (OAC). McFarlane, Graham and Richardson, working on the chick feed program at OAC, had used chloroform to remove all fat from chick chow. They noticed that chicks fed only fat-depleted chow developed hemorrhages and started bleeding from tag sites. Dam found that these defects could not be restored by adding purified cholesterol to the diet. It appeared that—together with the cholesterol—a second compound had been extracted from the food, and this compound was called the coagulation vitamin. The new vitamin received the letter K because the initial discoveries were reported in a German journal, in which it was designated as Koagulationsvitamin.

Where the record meets the 5 of Spades

A card is a calendar coordinate, not a cause. What follows sets one line of the card's own published language beside one sentence of the sourced record, paired by a documented rule. It is a resemblance offered for the reader to weigh — not a claim about Henrik Dam, and not a forecast of a Nobel Prize.

FAQ

What is Henrik Dam's birth card?

The 4 of Diamonds. February 21 maps to that card through the public Card Blueprints formula. The year of birth is not used.

Does a birth card predict a Nobel Prize?

No. These pages are coordinates, not fortune-telling. A birth card names a calendar day in a 52-card year. It does not forecast prizes, character, or fate.

Where do Henrik Dam's dates come from?

Birth date 1895-02-21 is the Nobel Prize API v2.1 day-precision date, verified against Wikidata P569 (CC0, day precision, Gregorian preferred). The two sources match. Year-only Nobel dates and Nobel↔Wikidata conflicts are dropped, not guessed. Page hooks and evidence come from the Wikipedia REST summary (CC BY-SA 4.0).
