delivered the opinion of the court:
The contract involved in this suit was before this court in the case of Preston v. Smith, 156 Ill. 359, Smith having sued Preston for the amount due for two years’ royalties under the contract. The appellant claims that the decision in that case bars the appellee from insisting upon the defenses sought to be set up in this action. But the questions in that case were different from those presented here. There it was held merely that Preston *184was bound to pay Smith $450 per annum for the two years during which Preston, before his death, had failed to pay, even though he did not manufacture or sell any goods under the patent, and that the privilege given Smith of canceling the contract on certain conditions did not make it an option contract, and therefore void under the statute. The expression used in the opinion, that “under the contract involved the sale and purchase were both absolute and complete,” must be interpreted in that connection, as is shown further by the reasoning in the opinion on this point. It was also there said that this was an executed agreement completely performed, and that a recovery cojild be had on the common counts. This must also be read in the light of the facts in that case. So far as the two years’ duration of the contract there involved was concerned, the contract was executed, and nothing remained to be done but to pay what had accrued under the contract.
Appellant also claims that this contract or agreement was an absolute sale of the patent right by Smith to Preston & Co., to be paid for in installments of at least $450 a year, as long as the patent right lasted. Of course, if this be so, the estate would be liable for the unpaid purchase money. But we cannot so construe the agreement. Taking into consideration all the terms of the agreement, we think it does not amount to a sale of the patent right by appellant to Preston & Co., leaving no interest whatever in the patent in appellant. On the contrary, he expressly retains the right to sell the article and the right to cancel the contract on certain conditions. Besides, the payments to be made are called “royalties” in the agreement, and are such in fact, Preston & Co. agreeing that they should be at least $450 per annum.
This brings us to the main question: Was this contract with Preston one of a personal character, which was terminated by his death? That contracts of a strictly *185personal nature terminate upon the death of the party by whom the personal service is to be performed, and that in such cases the executors or administrators are not liable for the performance of the contract, is a well settled rule of law. (1 Parsons on Contracts, *131; Addison on Contracts, sec. 396; Bishop on Contracts, sec. 600.) The only difficulty arises in determining whether or not a contract comes within the rule. As said in Shultz v. Johnson, 5 B. Mon. 497, this rule “is not defined and limited in the books with such precision as to render it always easy to determine whether particular cases fall within it or not.” Any contract from which it appeared that it was the intention of the parties that the service should be performed by the contractor in person alone, would terminate with his death. (Janin v. Browne, 59 Cal. 44.) Where distinctly personal considerations are at the foundation of the contract, the relation of the parties is dissolved by the death of him whose personal qualities constituted the particular inducement to the contract. The whole question in each case is one for construction, and depends upon the intention of the parties. (Billings’ Appeal, 106 Pa. St. 558.) In contracts in which performance depends upon the continued existence of a certain person or thing, a condition is implied that the impossibility of performance arising from the perishing of the person or thing shall excuse the performance. The implication arises in spite of the unqualified character of the promissory words, because, from the nature of the contract, it is apparent the parties contracted upon the basis of the continued existence of the particular person or chattel. Yerrington v. Greene, 7 R. I. 589; 84 Am. Dec. 578; Taylor v. Caldwell, 3 B. & S. 826; 113 E. C. L. 826.
In Smith v. Wilmington Coal Mining and Manf. Co. 83 Ill. 498, this court said: “Text writers, noting the decisions on this subject, state the law to be, that when the contract with the deceased is of an executory nature, and the personal representative can fairly and sufficiently ex*186ecute all that deceased could have 'done, he may do so, and enforce the contract. (1 Parsons on Contracts,— 6th ed.-—p. *131.) Common law authorities sustaining the doctrine are: Saboni v. Kirkman, 1 M. & W. 418; Wentworth v. Cook, 10 A. & E. 42. Exceptional cases arfe, when the contract is of a personal character, or requires, iu its execution, the exercise of peculiar skill or taste.”
In Marvel v. Phillips, 162 Mass. 399, the plaintiff, having invented an improvement in conveyors and an improved elevator, assigned his invention to Phillips, the defendant’s testator, taking from him an agreement in writing, by which Phillips agreed to manage the business for the joint benefit of both, to advance all funds requisite, and “to use all reasonable efforts to increase and supply the demand for the Marvel elevator and conveyor,—that is, to do all things which a wise and energetic owner of said patents, with ample financial ability, ought to do,” and in a later clause bound himself and his legal representatives to Marvel and his legal representatives. The court held that the agreement was discharged by the death of Phillips, saying: “The chief undertakings were personal in their character. He was to endeavor to create a profitable business under the patents, and to manage it, to advance funds, for the repayment of which he was to look solely to the business, to use all reasonable efforts to increase and supply the demand for the elevator and conveyor, and to do all things which a wise and energetic owner of said patents, with ample financial ability, ought to do. This implies personal skill, attention, and ability of a high order. * * * • The different parts of the agreement are not separable. * * * A contract to render such services and to perform such duties is subject to the implied condition that the party shall be alive and well enough iu health to perform it. Death, or a disability which renders performance impossible, discharges the contract. Neither Phillips nor his estate is bound to furnish a substitute, nor is the plaintiff bound to accept one.” *187See, also, Home Sewing Machine Co. v. Rosensteel, 24 Fed. Rep. 583.
In Oliver v. Rumford Chemical Works, 109 U. S. 81, there was an agreement by Morgan, for the use of whose administratrix this suit was brought by the Rumford Chemical Works, that he would manufacture their self-raising flour, and that he would use all his business tact and skill, and all other means necessary, to introduce and sell the same, and to make the sale thereof as large as in any way possible during the continuance of his license, and in case he failed to perform his covenants the Rumford Chemical Works reserved the right to revoke the license and terminate the agreement. Morgan died soon after. Mr. Justice Blatchford, in delivering the opinion of the court, said: “The right is granted to Morgan alone,—to him personally,—with an agreement by him that, he will enter on the manufacture of thfe self-raising flour, and that he will use all his business tact and skill to introduce and sell the flour. It is .apparent that licenses of this character must have been granted to such individuals as the grantor chose to select because of their personal ability or qualifications to make or furnish a market for the self-raising flour, and thus for the acid, all of which was to be purchased from the grantor. The license was made revocable by the grantor on the failure of Morgan to perform his covenants and agreements. We have not overlooked the fact that the privilege granted to Morgan was to continue for five years. This means no more than that he was to have it for five years, if he should live so long and if the patent should not have expired. But it cannot have the effect to impart assignability to the privilege, or to prolong its duration beyond that of his life.”
In this case it was “mutually agreed that E. B. Preston & Co. shall -push the sale of this swivel by advertising, exhibiting and soliciting, trade by their traveling salesmen or other employees; shall keep at all times in *188stock such quantities as will supply the market for demand, and to use their best efforts to create a large demand and a heavy sale of this article;” Appellant knew, when he signed this contract, that Preston was the whole firm, and he therefore contracted with Preston under the name and style of E. B. Preston & Co., and all the covenants and agreements in the contract were made with Preston alone, although, in referring to him, the plural pronoun is used, as grammatical usage required, its antecedent being “E. B. Preston & Co.” Mo inferences can be dra-wn from such use of the pronoun. Preston agreed to use his best efforts to create a large demand and a heavy sale of this article. Mo difference is perceived between this obligation and the ones assumed in the cases cited above, and this cannot be held to be such a contract that an executor would be bound to carry out. Neither does the election of appellant to rely only on the clause stipulating that the royalties should amount to at least $450 annually, alter the case. The contract is not sever-able. All its parts must be construed together, and the evident intention of the parties was, that Preston’s “best efforts” would or should create such a “large demand and heavy sale of this article” that the royalties on its sale would amount to $450 annually, as a minimum. It would be unreasonable to hold that Preston’s executors should be bound to continue his business for more than ten years in order to carry out this contract. It is well settled that executors are not authorized to continue the business of their testator unless it clearly appears from the will that such is his intention, and if they do so without authority they do it at their own risk. The will of E. B. Preston will not bear such construction. All the expressions used in it would be entirely proper and applicable in the will of any person possessed of large property, and impose no other duty on the trustees than to properly care for the property. The contract having been determined by the death of Preston, such event fixed the time to which *189he was bound to pay, and bis executors would not be liable under it beyond such date.
There are some other questions raised by appellant, but as they were not submitted to the trial court by any of the propositions asked to be held as law, nor raised in the Appellate Court, they come too late here.
The judgment of the Appellate Court is affirmed.
Judgment affirmed,.
