History
Bilateral renal agenesis (BRA) was first recognized as a defect of human fetal development in 1671 by Wolfstrigel.
In 1946, Edith Potter (b.1901 - d.1993) described a series of 20 cases with absent kidneys, noting the characteristic appearance of the head and lungs. Up until this time, the condition itself was considered to be extremely rare. However, in part to Potter's work, it has come to light that the condition presents far more frequently than previously reported. Potter analyzed approximately 5000 autopsy cases performed on fetuses and newborn infants over a period of ten years and found that 20 of these infants presented with BRA, all of which had distinctive facial characteristics. These facial characteristics have subsequently been termed as being known as Potter facies. From her analysis, she was able to deduce the sequence of events that leads to what is now known as Potter sequence.
Potter went on to become a pioneer in the field of human renal development and her contributions are still employed and appreciated by clinicians and researchers to this day.

Famous quotes containing the word history:
“Free from public debt, at peace with all the world, and with no complicated interests to consult in our intercourse with foreign powers, the present may be hailed as the epoch in our history the most favorable for the settlement of those principles in our domestic policy which shall be best calculated to give stability to our Republic and secure the blessings of freedom to our citizens.”
—Andrew Jackson (1767–1845)
“America is the only nation in history which miraculously has gone directly from barbarism to degeneration without the usual interval of civilization.”
—Georges Clemenceau (1841–1929)
“In nature, all is useful, all is beautiful. It is therefore beautiful, because it is alive, moving, reproductive; it is therefore useful, because it is symmetrical and fair. Beauty will not come at the call of a legislature, nor will it repeat in England or America its history in Greece. It will come, as always, unannounced, and spring up between the feet of brave and earnest men.”
—Ralph Waldo Emerson (1803–1882)
