Daniel Paul Schreber (1842-1911) was a senior German judge and jurist who formulated a unique juridical theology of private life and developed a critical account of oikonomia, the practice of governance and administration. But their theoretical work was largely ignored due to their mental illness and desire to be a woman in a time inhospitable to transitions. Now, Schreber's Law looks beyond Judge Schreber's mental health to reappraise their distinguished contribution to legal theory.
