Hubert J. P. Schoemaker (born March 23, 1950 in Deventer, Netherlands – died January 1, 2006 in Paoli, Pennsylvania) was a Dutch-American chemist and biotechnological pioneer. Schoemaker was a co-founder and the president of the Bio-tech company Centocor. He helped develop Remicade, a drug to treat auto-immune disorders like Crohn's disease and rheumatoid arthritis. After selling Centocor to Johnson and Johnson for $5.2 billion in 1999, Schoemaker went on to form Neuronyx, Inc., a biotech company focused on developing cellular therapies. As of 2007, Neuronyx is in clinical trials testing adult bone marrow-derived cells in heart attack patients.
