Biography

In 1864 he became a chemical laboratory assistant at Philadelphia High School.[2] He was assistant to Benjamin H. Rand at Jefferson Medical College (1865-1870). He obtained his M.D. in 1869 from Jefferson Medical College.[2] Leffmann was chemist to the coroner of Philadelphia (1875-1880) and district attorney (1885-1897).[1] He was a chemist to dairy and food commissioners of Pennsylvania. He married Fannie Frank in 1876, they had no children.[1][3]
Leffmann was lecturer on Toxicology at Jefferson College (1870-1882), lecturer on botany at Wagner Free Institute of Science (1874-1875) and Professor of Chemistry (1885-1903).[2] He was microscopist of Pennsylvania State Board of Agriculture (1877-1905), professor of chemistry at Philadelphia Polyclinic (1883-1898) and pathological chemist at Jefferson Medical College Hospital (1887-1905).[2] He received an honorary Ph.D from the Wagner Free Institute of Science in 1874 and a DDS from Philadelphia College of Dental Surgery in 1884.[2]

Criticism of Christianity
Leffmann authored a pamphlet The Mental Condition and Career of Jesus of Nazareth in 1904. He argued that Jesus was a megalomaniac and that much of his phenomena could be explained by hypnosis and suggestion. Leffmann was an advocate of the swoon hypothesis, arguing that Jesus did not die on the cross, but was "tenderly cared for, probably by the mother and brothers whom he had disowned and scorned, and quietly buried after his death, which may have occurred very soon afterwards."[6]
