delivered the opinion of the Court.
Thе principal question presented by this appeal is, as stated in the application: “The Court (of Civil Appeals) erred in holding in effect that the payment of a liquidated, undisputed item, admittedly due and owing, constituted a considеration for the release of a disputed item under the supplemental contract of insurnace in question.” We have concluded that the point is good.
There is little disputed about the facts, and petitioner says that the precise question has never been here.
On August 26, 1935, respondent issued to Carl C. Hallmark a life insurance policy for $1000, with petitioner as beneficiary. For an additional consideration the policy carried a double indemnity benеfit if the insured should die “as the result of bodily injuries caused directly, exclusively and independently of all other causes by external, violent and accidental means.” That he duly paid all premiums and that the policy was in effect at insurеd’s death on. April 7, 1948, is undisputed.
The jury found that Hallmark died on April 7, 1948, as the result of a- coronary occlusion; 'that his death resulted from bodily injuries caused directly, exclusively and independently of all other causes, as the result of a seriеs of shots or innocu-lations given to him from March 21 through April 1, 1948; that these injuries to Hallmark resulted from external, violent and accidental means as a direct result of the series of shots or inoculations given to him from March through April 1; that these injuries were evidenced by a visible bruise or wound on the exterior of his body, and that Hallmark’s death did not *294 result directly or indirectly from any bodily or mental disease or infirmity.
Thus we have an insurance contract which is neither equivocal nоr ambiguous. It promises in plain terms that insurer, in addition to the amount payable under the life insurance policy, will pay to the beneficiary or beneficiaries under the policy an additional $1000 in the event of the death of the insurеd resulting from bodily injuries caused directly, exclusively and independently of all other causes ****.”
This language created two separate and independent demands under the contract, with the conditions of liability as well as the amоunt of liability plainly stated; and it is $1000 or nothing under either. Yet respondent seeks to avoid payment of the $1000 for accidental death on the ground that it had paid the $1000 due for death regardless of its cause.
Cases holding contrary to the conclusion we have reached in this case disclose material, differentiating facts.
Illustrative of cases urged in support of the contention of nonliability because of settlement is Washington Nat’l Ins. Co. v. Cook, Texas Civ. App.,

In the Heavin case, supra, (
W. O. W. Life Ins. Society v. Smauley, Texas Civ. App.
Another pertinent authority is American National Ins. Co. v. Walker, Texas Civ. App.,
The late case of Connell v. Provident Life & Accident Ins. Co.,
There remains but one other matter to be considered: re *297 spondent’s assertion that petitioner is estopped to claim the additional $1000 accidental death benefit.
The claimant’s statement and death certificate, which were furnished to respondent by petitioner on April 22, 1948, stated that death was due to coronary occlusion and circulatory failure. The portion of the death certificate form which recited “If not due to disease, specify whether accident, suicide or homicide” was left blank. About eight days later petitioner received the $1000 payable under the policy in the event of natural death, and executed an instrument releasing respondent from all liability on the policy together with all supplemental contracts and agreement pertaining thereto. Respondent contends that in reliance upon these instruments furnished and executed by petitioner, it paid out its money exactly as demanded by petitioner, released its reserves, changed its books and records, and closed its file on the case without making a full investigation, and that petitioner is therefore estopped to assert the present cause of action.
As we view the case, it is not necessary for us to decide whether respondent has so changed its position as to work an estoppel against petitioner. It is generally essential to the applicatiоn of the doctrine of equitable estoppel that the person claimed to be estopped shall have had full knowledge of the real facts at the time of his representation, concealment or other сonduct relating thereto and alleged to constitute the basis of the estoppel. Richey v. Miller,
No estoppel issues were submitted to the jury or requested by respondent, and wе do not think that the circumstances mentioned above establish conclusively that petitioner knew such facts or was guilty of such negligence in failing to know them as to work an estoppel against her in this case.
*298 The judgment of the Court of Civil Appeals is reversed and that of the trial court is affirmed.
Opinion delivered January 25, 1956.
