Elizabeth of Hungary  The Ohio Anglican.blog
The numerous "St. Elizabeth's Hospitals" throughout the world are for
the most part named, not for the Biblical Elizabeth, the mother of
John the Baptist, but for this princess of Hungary. She was concerned
for the relief of the poor and the sick, and with her husband's
consent she used her dowry money for their relief.

During a famine and epidemic in 1226, while her husband was away in
Italy, she sold her jewels and established a hospital where she nursed
the sick, and opened the royal granaries to feed the hungry. After her
husband's death in 1227, her in-laws, who opposed her "extravagances,"
expelled her from Wartburg. Finally an arrangement was negotiated with
them that gave her a stipend. She became a Franciscan tertiary (lay
associate) and devoted the remainder of her life to nursing and
charity. She sewed garments to clothe the poor, and went fishing to
feed them.
