# Sophie Hélène Béatrix dies on 19 June 1787 as an infant death in Marie-Antoinette’s household

Date: 1787

## The fact

Britannica dates Sophie’s death to 19 June 1787 after the 1786 birth. Physicians share the file. It is not a national epidemic series and not a Revolutionary killing.

It is one event.

## Context

Sophie’s birth row is neighbouring. Louis-Joseph’s 1789 death is a later child-death row.

[Marie-Antoinette](/people/marie-antoinette)’s documented role is bounded by other offices and collaborators named in the sources below. Sharing a field with them is not a reason to drop a documented act, and it is not a reason to assign later consequences done in the name after death.

High infant mortality even in elite households; court mourning was public news.

Named person as heading of the dated public instrument. Later editors, museums, printers, or offices share publication. Complex where later carriers are the surviving public file.

## Evidence and sources

Britannica’s Marie-Antoinette life independently dates Sophie’s 1787 death; Versailles child lists align.

Official or archival record: Britannica — Marie-Antoinette (https://www.britannica.com/biography/Marie-Antoinette-queen-of-France; Encyclopaedia Britannica).

## Significance

An infant royal death is a health-capacity failure path inside the household medical file.

## What is established and what is not

Established: 19 June 1787 death date in the biography file. Not established: a precise modern diagnosis beyond the received record.

What would change the picture: a contradictory original with a different date or name, or a measured series that can be argued, with lag and alternatives, as a consequence of this instrument rather than of later institutions.

The date is the date of this instrument, not a licence to back-date every later harm or benefit.

Established here: a sourced, dated public instrument with a named contribution by Marie-Antoinette.

They are not a public rating.

The driver `health-system-capacity` is attached because the mechanism named in Significance follows from this instrument, not because a standing list of welfare headings needed another tick. Marie-Antoinette did not file a later UNESCO form, a later Loeb colophon, or a later museum label as a personal act. A portrait or conventional bust is not this mechanism. Allegation, reconstruction, and established occurrence stay distinct. Do not merge with Louis-Joseph’s 1789 death. Keep the carrier date of later English distinct from the received historical year stored in the date field. Do not read a later English edition as a recovered autograph of Marie-Antoinette.
