Thomas Shipley was one of the founders of the American Anti-Slavery Society, and was an active agent in those stirring movements which soon aroused the nation to a full consideration of the enormities of Slavery. He was a prominent member of the Anti-slavery Convention, which assembled in this city in 1833, and a signer of their declaration of sentiments.

During the last few years of his life, he was more devotedly engaged in his abolition labors than at any previous period. It was his constant desire to diffuse the principles which had been so fearlessly proclaimed by the Convention, and to encourage the formation of Anti-slavery societies throughout the sphere of his influence. He was one of the most prominent members of the Philadelphia Anti-slavery Society, which was formed through much opposition, in 1835, and he steadily adhered to its meetings, notwithstanding the threats which were so loudly made by the enemies of public order.

In the midst of the popular commotions and tumults, which marked the progress of Anti-slavery principles, he stood calm and unmoved. Having been long known as a firm friend of the rights of the colored man, and being amongst the most efficient public advocates of his cause, he was of course subjected to the revilings which were so liberally heaped upon the Abolitionists at that time. His name was associated with that of Tappan, Birney, Green, Jay, Garrison, and other leading Abolitionists, who were singled out by slave-holders and their abettors as fit subjects for the merciless attacks of excited mobs.

In several attempts which were made in this city to stir up the passions of the ignorant against the advocates of human rights, his person and property were openly threatened with assault. Such menaces failed, however, to deter him from the steady performance of what he believed to be a solemn duty. Being fully satisfied of the truth of the principles which he had espoused, he relied with unwavering confidence upon Divine power for their ultimate triumph, and for the protection of those who advocated them. When his friends expressed their anxiety for his safety, he always allayed their apprehensions, and evinced by the firmness and benignity of his manner that he was divested of the fear of man, and acted under the influence of that spirit which is from above.

The active part which Thomas Shipley took in Anti-slavery movements, did not diminish his interest in the prosperity and usefulness of the old Pennsylvania Society. He was a steady attendant on its meetings, and exercised his wonted care on all subjects connected with its interests.

A short time previous to his death, his services were acknowledged by his fellow-members, by his election to the office of president.

The incessant and fatiguing labors in which he was engaged, had sensibly affected the vigor of a constitution naturally delicate, and rendered him peculiarly liable to the inroads of disease. He was seized in the autumn of 1836, with an attack of intermittent fever, which confined him to the house for ten or twelve days, and very much reduced his strength; while recovering from this attack, he experienced an accession of disease which terminated his life in less than twenty-four hours. But a few hours before his death, he inquired of his physicians as to the probable issue of his case; when informed of his critical condition, he received the intelligence with composure, and immediately requested Dr. Atlee, who was by his side, to take down some directions in regard to his affairs, on paper. In a few minutes after this, he quietly lapsed into the sleep of death, in the morning, on the 17th of Ninth month, 1836.

His last words were, "I die at peace with all mankind, and hope that my trespasses may be as freely forgiven, as I forgive those who have trespassed against me."

To all who knew him well, of whatever class in the community, the tidings of this unexpected event brought a personal sorrow. It was felt that a man of rare probity and virtue had gone to his reward. But to the colored people the intelligence of his death was at once startling and confounding. Their whole community was bowed down in public lamentation, for their warmest and most steadfast friend was gone.

They repaired in large numbers to the house of their benefactor to obtain a last glance at his lifeless body. Parents brought their little ones to the house of mourning, and as they gazed upon the features of the departed, now inanimate in death, they taught their infant minds the impressive lesson, that before them were the mortal remains of one who had devoted his energies to the disenthralment of their race, and whose memory they should ever cherish with gratitude and reverence. When the day arrived for committing his remains to the grave the evidence of deep and pervading sorrow among these wronged and outraged people was strikingly apparent.
